Big horsepower 318 builds

Can't believe I'm entering this thread-

I personally don't think it would be very easy to make an honest 500hp stock stroke 318 on pump 91-94 fuel and retain civil manners. This engine is going to be more of a race engine. That being said I would love to see someone attempt this build-heck I would throw my hat into the ring (as I do in fact have a '83 318 core to start with) if it weren't going to cost me my first born.

I'd target 11 to 11.5 -1 compression and use whatever fuel it takes so there goes the pump fuel stipulation. Maybe it will be ok on pump, maybe not IDK.

If staying iron than some EQ's or RHS's need to be found and ported and every port needs to be tested and ported and tested again and ported. Much like I did on my 2011 EMC 371--This alone took a month of work before I felt I had the heads right. I'd do something like a .050" to zero angle mill on the heads and use a 2.02-2.055 intake valve-hollow stem or 5/16" stem. The chamber is going to wind up very small so either a flat top piston or a small conical dish might be needed to reign in the comp ratio<<<(Not sure about that I haven't run any numbers yet) I'd spend some time on the crank profiling counterweights and look at making a crank scraper. Cam could use a SFT but its going to wind up on the large RACE side. A custom SR would make life much much easier. Something like 254-258 @ .050" .660-.680" on a 106-its gonna idle @ 1150-1200 rpm and be very hairy. Keep the rockers simple and light and probably go with T&D's depending on the head casting. Scat I beams get the nod here if we are trying to keep it as off the shelf as possible with an ICON or SRP piston, although I see Mahle will now do custom stuff so maybe a nice modern Mahle with their amazing 1mm/1mm/2mm ring package. I'd use my Weiand X-celerator because those intakes just plain work--wish they still made them. Carb could be a 650XP or a 750XP both of which I have.

That's it in a nutshell--I've glossed over the frame work but have left out a lot of little details. It would probably make 498 HP in the end and the internet would consider it a fail. J.Rob
