305 HO heads on a 350???

Hi, guys this is my 1st post on here and I have a Question. I just got a set of 305 HO heads: 14014416 and #624. They are good heads but I would like to know if they will work on a 350 bored 40 over with flat tops. Also need the best street cam and lifters for it. The motor is going in my 1927 model A Rat Rod so it is just a cruiser not a racer. It has 373s in the rearend and a 2 speed power glide trans and we drive it on the hiway quite a bit. Like I said its not a race car just a strong cruiser. All your ideas are greatly appreciated!! Chasman

Really would love to hear an answer to this as I'm about to do the same this weekend....

kingofny1997 Got the gasket in today, bought some high temp silicone for the extra seal...pretty fine with putting everything back together

just worried about the distributor hook up and lining up right to start up, tdc is reached (#1 piston is TDC....) also before I took out the distributor I labeled number 1-8 spark plug points on the distributor

Can end up with a locked up lifter plunger and no cylinder compression
The lifters fill all by them selfs very quickly on engine start up.
Just coat the foot with moly paste oil up the rest of it and drop them in.

Be sure to oil up the rocker arms too.

Dipping the roller wheel end of roller lifters in oil and letting the oil soak in to the roller bearing is good stuff but filling the internal cavity in the lifter is not.

You can soak your roller rocker arms in oil to your hearts content.
Ok just ended up ordering a new timing gasket and cover with 10 new screws. And the bottom gasket of the timing cover.... my question is what seal or gasket filler maker do I use for the timing cover, also what sealant do I use for the fuel pump, water pump, intake manifold if different...

Use a converntional dino oil preferably with a high zinc additive.
Many "racing oil" oils have more zinc. Mot all off the shelf retail automotive oils have less zinc now.
GM EOS or Crane Super Lube break in lube is good stuff too.
Save the royal purple for latter.

But reguarless you want the moly paste (moly disulfide) on the cam lobes.

Get the engine started and running quickly without a lot of cranking and run at 2000+rpm for about 1/2 hour. SO the cam gets friendly with the lifters without scuffing.

You can get the moly paste under various bands and packaging.
Most automotive lubricant companies make it.

Don;t forget the dip the lifters in oil ( do not fill the lifters just dip them.
And oil lube the rockers. The whole idea is to avoid dry start scuffing.
I ordered the crane cam moly lube, and gaskets I needed,

But my question is you said "Dip the lifter, (do not fill the lifters just dip them)
I've always heard to fill up a little bucket with motor oil and drop them in their and let them sit in their for 3-6 hrs, then when going to install put the assembly lube on the bottom..and install..

kingofny1997 Ok, well got the cam today with the lifters , I got permatex ultra slick red assembly lbe, and the lifter came with assembly lube do I use my assembly lube or the one that came with the cam

kingofny1997 Just ordered the sum-1103 with lifter at 99.95 and hyped about it,
Wanted to know since I already have the fuel pump out due to removal of camshaft, should I get a new one since, the car sat for 6 yrs, and at anytime it could go and since I need to put a new gasket since I took of the fuel pump...also is their a gasket kit for reasonable price , instead of buying everything separate (valve,intake manifold,water pump,fuel pump, timing gasket set) ????

Also I read on a couple of these sites that they recommend to not run synthetic oil while break in, but I have 10w-30 royal purple synthetic oil (no zinc), so what should I do (valvoline vr1 oil with the break in cam oil) or what help..thanks firebird and fellas

Howards has very similar equal cams at good prices too.
I like Howards cams
. have a look www.howardscams.com

Yes your milder cam choices the top end will tapper off a good bit sooner.

The cams I selected for you are good to 5000+rpm.
I have used then all at one point or another.
Thanks Summit 1103 defently considered, seen a video of how it sounds on a chevy 350 sweet, also for $100 for the kit, great Deal!!

kingofny1997 Summit 1103 (quest-operatin rpm range1600-5200) not sure wht that means
(also FAIR IDLE)
Comp 265deh (expensive)

Elgin version e923m (similar specs to sum 1103, but smooth idle!great deal)

(would this go with my setup??????)

Speed pro CL1014R (similar specs dies at 4000rpm, ) not sure if it's good since it dies at 4000rpm


Bottom 2 cams were just some that I seen on this site after some hard searching,

New cam choice:
What car? what gear ratio? what do you want the motor to do different, than before? Exhaust system?
Whats done to the 305 heads?

I would swap that intake for a Performer RPM dual plain hi-rise manifold.
Big difference in usable torque.
1973 Chevy Nova, 3.08, Nothing special, just sound nice if alittle power can be added without changing springs or pistons GREAT!!, Headers with Stock pipes to the back, not sure whats done to the 305 heads car was sold by wife since husband passed away..

Looking for a new cam, looking for something mild, but that doesnt require change of springs or pistons..

My cam i just removed says cwc 1517, Nice sound too it, looked everywhere for specs or replacement and doesnt appear anywhere, what can you guys recommend

(P.s i know my compression is higher than stock due to 305 heads, car came with this setup)
