081/416 heads that make afforable power.

I did a couple builds that some people would like for the money. Budget Engines short block 350 (355) $450 out of Cleveland Ohio a Stock NEW rebuilt engine (0 miles). Rebuilt resurfaced 14101081 (416) mildly ported and polished with unshrouded 1.94 and 1.6 valves, 62cc chambers. $200. Good used Crosswind intake port matched 4 port 1" spacer $75. Rebuilt edelbrock 1405 without choke $50. Comp Cams 275DEH cam kit $130 , summit used roller rockers $50. Mallory complete HEI ignition with wires $160. Summit headers $75, spectre engine dress up kit $60. Bulldog rebuilt starter $25. Powerhouse stock balancer and flex plat $50. Felpro gasket kit $40
flow numbers
Intake Exhaust
.200- 127 103
.300- 179 136
.400- 208 151
.500- 226 164
.525- 233 169
.550- 235 171
.600- 229 170

Max HP was 432.6 @ 5500 rpms
Max TQ was 446.8 @ 4500rpms
THIS IS AT the CRANK!! grand total rounded $1,400.00
This had 3" exhaust with dual cherry bomb Xtreme mufflers. $500 (not a must have)
Yes other heads would make more power but can you get them in the price range? The engine shop I deal with said that EQ 200cc vortec and a bigger carb would make just under 500HP with this same set up. That Would cost around $800 more give or take.

Can`t advertise on here so it won`t be long before a mod removes it. Just letting you know. I`ve heard the storys on 305 heads being magic by more than just you on here and when I see some drag strip proof, not numbers posted I`ll believe it. If it were as easy as it`s made out to be the aftermarket companies that make heads wouldn`t even be in business as nobody would pay that when they could home port there own heads and make the same power.

A lot of people don't want to do any work themselves these days. I've been through so many heads that I've lost count. The reason I talk about the 305 heads is that most of the time you can buy a whole engine for $50. I've built 305, 307, 327 350's. Ive gotten heads for Free as well. just a little time and a little money you can have a good engine. I built a very mild 305 a couple years ago and 313HP at the rear wheels of my 86 Monte Carlo. Ran 13.61 in the quarter. Plus 18mpg average. I know most aftermarket heads are good. But there is still a love for true Hot Rodding in this world. I have a 355 built with 601 heads but that is going to change this spring. I am putting a .600 solid roller cam with Ported EQ200cc heads with 2.05 x 1.6 valves. I work in an engine machine shop. I try all sorts of new things on my free time. I am doing a set of 081 heads (I like the 083's better) with 7mm valve stems. I did it with a set of light ported 302 ford heads and it made a world of difference.

I have done quite a few 305 head on a 350 build.
I get the same port flow as you with 1.94x 1.60 valves in the #416 heads. Takes full porting, not a little or mild porting. I get comparable power with a bigger cam but not with such a small cam as the DEH275.
430hp needs a 244-255@.050 max street/bracket cam. I would expect 390hp (and great torque) from the 275DEH which is still very good.

There is no magic, just hard work (porting and preparation). You'll find lots of resistance to this, here.

So I don't get it, are you making a point, selling this stuff or what?

FWIW, where do you get a set of 416's that are ready to go for $200? I've been looking for a set for my 305 project...

Where can you get a 355" short block for near $500 in ohio ? Anywhere ?

My pricing for a 350 8.5:1 short block was around $1100 for replacement style.

Some people would like an idea on what it will cost to build and engine. I find heads all over. I get them from craigslist, ebay, affordable auto-parts, and (pull-a-part $50 a set). If you want some that are already and shipped to you look up allied motor parts (there are several other companies too). They will get you any oem head you want and build them the way you want. I payed $280 for a set built and shipped to me with a 1 year warranty. You Can get the Short block at budget engine builders. A complete basic long block is $895. They will build them any way you want for a good price. I have three engine I am building right now. A 307, 305 (being built the same to see which one make better power) and a 355 (Ported EQ200 with a comp .598 solid roller 1.6-1.5 roller rockers, RPM ultralight crankshaft, CPR ultralight rods, KB123 pistons 12.1:1. Just did a 302 and 460 ford.

There's a big difference between a quality-built engine and one for a "good price". A set of heads for 280 bucks with a one-year warranty are worth just that and one will probably have to use that warranty. Anybody hawking cheap, production rebuilt engine parts probably has no idea of what quality engine work looks like..................

I advise you to quit quoting prices in your posts. This is borderline advertising. I know people want to know what prices may be, but they can PM you for your prices.

Guess that's whats wrong with the world. I am sorry that you feel that way. I too work in an engine machine shop. I am very picky about what I order and who from. I have learned a lot about other shops as well. We try all kinds of stuff to see how well it works. It mostly cost the shop a little time and very little money. Things done right you can learn a lot. For Very Little Money. Most people do what they can with what money they have. There are more people who try than people that are supposed to be PRO's. Knowledge is more power than money in almost all forms.

I know a guy that builds good engines for a relatively low price and he deals with other local shops. Not saying that this post is necessarily not BS, but that I have personal contact with similar people.

I also finished a ported set of 416 heads for a little under $300 including a valve job, surfacing, and screw in studs (paid someone else to do most of the machine work).

It doesn't mean the original post is 100% accurate, but it is certainly feasible.

As for the dyno numbers... I've seen ones that I consider much more of a stretch.

It costs me $460 to fully "street/strip" prep my #416 heads.
I do all the hand porting, cleaning and assembly and many of the mods by hand.
New manley valves, hi perf springs,seals, shims set, 3 angle valve job,
guide boss machining, surfacing, guides as required.

The machine shop I work at builds about 2 engines a day most of them are import engines and not hi-performance. The shop I deal with is a pure through and through race shop. Very highly respected engine machinists and builders for all out competition. Here is one of the engines I built ( http://nhraunleashed.com/profile/HDa...ource=activity ) go to this link. I have yet to dyno this one but will hope to have time this spring.

you guys are lucky... the cheapest quote that I've gotten for the same work locally with machining for studs and guideplates, cleaned up stock valves instead of new, me supplying all the parts was $7xx + I think it was $18/guide if any needed to be replaced.

I had a longer reply written, but nutshell, I used to work at a speed shop locally and even "at cost" knowing the people at the machine shops I couldn't get the kind of pricing you guys are talking about, and I know what I was looking at and the quality was no better than what you'd get paying $400 to Aerohead (Indy Cylinder head) to get a set of 602's all done with no core charge.

In the end, I've been spending money on tools to do my own work, and I've saved enough money over the last few years to accumulate some nice tools...

The work I get is really nice, I used to go to a shop that charged me more, and I was happy to pay it, I just found a foot in the back door. There are only a few people that get the rates I do from him- because I do port work for him and I get more machine work done than most people.
