BigHazzard Okay well i have one sitting in my garage. its a early 70's boat tall deck 427 with 67 oval part heads. I am a newbe to this. Played with small blocks some but it was usually for 4x4's. So what I am seeing is that I just need to get a new crank, rods, and pistons and this thing will be pretty nasty. You guys have some awesome info here and i really appreciate it

BigHazzard Okay I just want to say I thank my lucky drag stars for you guys cause i picked up one of these motors with a set of 67 heads on it and i started reading and a lot of people are saying boat anchor... but after reading this I am really stoked. because of budget limits I think i might have to go to just pistons for now but I see my piggy bank getting a work out to start the next stage of this motor.

oops sorry i forgot to post the link to the pistons i was talking about, theyre a stock 4.250 bore, just to save some money on machine work and not have the bores punched out.

im not sure if i punched the numbers in to the calculator right or not, but it says it would be 10.25: 1 CR, please let me know if im wrong.

techinspector1 No, it's a 505 with +0.100" pistons. (.7854 x 4.350 x 4.350 x 4.250 x 8 = 505).

b00tz i think these pistons would go well too, if my math is right they would give about 10.2: 1 compression with a 119 cc head, somebody let me know if im wrong, but that would be for a 482.

Guy Hiltz They look like nice rods,the low price gotta make you wonder though !! But,who knows,they might be just as good as the Eagle ones.

techinspector1 Guy, your post got me to looking for alternative low-buck rods. I, of course, don't know anything about them, but here is a set of 8 for $270. This engine build is limited to 5500 by cam choice, so they might work ok.

techinspector1 I'll get right on that Guy.
08-27-2009 05:18 AM
Guy Hiltz No problem.But now I'm waiting for you to build one of these tq monsters nd put it on an engine dyno and see what you get for #'s,then send it to me and I will do a tire test for you LOL

techinspector1 Thanks for the heads-up Guy. I should have known that 200 bucks for a set of 6.535" rods was too good to be true. I have edited the post to include the rods you linked.

Looked at the trans you linked....WOW....paddle shift too. I've driven a paddle shift and it is FUUUUUUUNNNNN.

Guy Hiltz Tech,that looks like an awesome build up,but it appears that your choice of rods arent real cheap.The price shown in your link is for 1 rod,so that puts the price up a bit,almost $ 1600.00 for a set of rods !! Heres a link from Lunati;

But cheaper ones are available,such as these;

Got to love that torque curve,over 500 ft/lbs from 2000-5500 rpm.Imagine that in a lightweight car with this tranny;

You'd have a lot of fun !!!

123pugsy Thanks Tech.

I don't see anything "better', just a matter of preference.
I installed a TPI on my 76 p/u and I just love the injection now.

techinspector1 That system apparently uses the same high-rise, dual-plane intake manifold that I used on the software pulls, but provides another 150 CFM over the 850 carb I used. Plugging 1000 into the program, I find another 1 or 2 hp and ft/lbs at 2000 and an additional 6 hp at 5500 and 6 ft/lbs at 4000.

It's pretty pricey, but if you see advantages over carburetion, go for it.
