Hey all, I have some bare Edelbrock heads on the way here for my little 318.
I read this article. I'm sure you're all quite familiar with it
http://www.carcraft.com/techarticles/ccrp_1110_pump_gas_small_block_mopar/
Those cylinder heads look like works of art and I was wondering what something like that would go like on a little 318.
Before everyone says "stroke it" or "get a 360" I'd like to point out that this engine has Steel crank, H beam rods, Domed forged pistons and a fully balanced and blueprinted rotating assembly.
Now, I believe 450-500hp is possible and even streetable with a 3500 stall and 3.7 gears on a 25 inch tall street tire. (98 octane fuel helps too)
The cam I'm looking at is a solid grind, 242/248 @ .050 .540"/.550 lift. 114LSA 113ICL
This might seem mild but the 114 lobe separation should help it rev clear to 6500RPM before it makes peak power Assuming I have enough head flow at lifts up to .540"
Obviously the valve springs would need to be a lot lighter. but as far as the 2.08/1.6 chebby valves and titanium retainers go, should it all be compatible/optimal?
I understand I would probably have to notch the bores even though they are +.030".
The porting, tubing and machine work. how much of it would be worth while and how much of it would be wasted on an engine with only 76% the displacement and 80% as much valve lift?
I understand this was an "all-out" type build but it still flows awesome numbers up to .550"
What are the potential pitfalls of putting "too much" cylinder head on an engine?
