More power outta 460 with good alum heads or stroker with iron heads?

Post  2L8ULOST on October 20th 2010, 6:52 pm

Im really wanting to get into the high 500 to low 600 range on torque, was wondering if this would be better just building a 460 stock stroke and rod length with good h/c/i or building a stroker like 514 or 521 with iron DOVE heads with a good cam and intake jw im kinda new to this BBF thing THANKS IN ADVANCE! IM wanting a car i can drive to the track and possibly to shows when racing seasons off!

Welcome.
And go to the proven builds section, or the top here on engine tech. Dave Ohagens build up stickeys listed will get you there.
A 472 .080 overbore X 3.85 stroke and DOVE heads should get you there economically.
Goodluck.
Al

I'd do the stroker, no replacement for displacement

Stroker all the way! Put a good bottom end in it that way when you want more power (and you will) you won't be worried weather the bottom end will hold it.

I'd do the heads, 500-600ft Lbs is doable with stock 460 dimensions, but to make power you need to move air. Plus you'll lose some weight with something like Ford Racing SCJ's or P-51's.

Who sells the SCJ heads and P-51's ? I've seen the SCJ's in Summitt but not the others .

Thanks

stroke it FTW!!!

I would stroke it because when you want more power which will b about a week all you gotta do is bolt on some tfs streets heads

with stock bottom end and good heads your maxed out

my dove headed 545 small cam makes what your lookin for for around 3000-3500 bucks then throw on the street heads bam lot more power

If I had to do it again I would go with a forged 4.3 crank at around 9.5 to 1 and 4 bolt main so I could turbo it later

If you think you need more than 460" to blow the tires off most street rides you need help.

650-700hp is pretty doable without stroking it on pump gas.

Dave is pointing you in a good direction here IMHO. You can get a real respectable hp with good heads vs. the tq the stroker makes, and use the better hp with proper gears to multiply the torque the engine makes. It's all about the total package. In a lightweight car, you don't want to make too much tq and have nasty street manners. Cool

I looked at the same thing that you are trying to do.
I went with a set of P-51 heads with a .030 over 460. Now my application is different. I am going be strictly bracket racing.
read this article/add at jon Kaase's web sight.
http://www.jonkaaseracingengines.com/component/content/article/40-kaase-products/188-kaase-p-51-cylinder-heads.html
If you look at the numbers on the cam, it is not that big. 255/262 at 0.50 lift, it is a roller with a lot of lift but I think that similar HP numbers could be made with a big solid.
Also, I got my heads from Lem Evans. He sells both the P-51's and the SCJ's and he is a super guy. When I did mine, he didn't have the super deal on the SCJ's like he does now. I don't know what your budget is but a call to Lem would not be a bad idea. The guy has tons of knowledge.
just my 2 cents.
