more slant6 hp!
I think I'm going to enjoy the slant for a while and then drop a v8 in...I apologize to all who've offered advice...I think tuning a /6 to get v8 hp is way out of my expertise
building a high powered slant isn't terribly hard tho. You have the desired slant block the 68-75 where pretty much all components are forged, except for the pistons. A company called Venolia makes different piston sizes(Std. .030, etc etc) in forged pistons. That is what I'm installing in my motor because after I do that I'll be cleaning the head up a bit smoothing out the cast iron and making it flow somewhat decent. I have my combo all figured out and it will run me about 5 or 6 grand to build it the way I want it. 8 to 1 compression ratio is perfect for a turbo engine which is what a stock slant came with. It's difficult and expensive I have to agree. But not out of anyones reach. My combo should be able to reach 500 hp with the right tuning and fuel and I should be able to tune it higher to make more power with higher octane fuel. I'm sure building a small block to that much would cost around the same.
My combo is running in essentially stock 225 slant 6, with forged pistons, ARP studs and bolts everywhere I can get them(bottom end, and head bolts are all available) I'll be running an ignition setup off a Ford Windstar because coupled with my MEgasquirt ignition system It offers the best control because as a turbo boosts you need the timing to change in small amounts to fight against detonation, because detonation = kaboom. I'll be running a Offenhauser intake drilled and tapped for fuel injectors in the intake runners for improved fuel distribution(a huge problem on single carburator slant intakes which is why a triple weber setup improves driveability and power) and a stock throttle body off a modern magnum engine. The turbo manifold? ether custom or I'll buy one if someone starts making them which will be hooked up to a single T61 Garrett ball bearing turbo(the most expensive part of this whole project last i checked these are 1600 bucks each)
As you can see it's taken a ton of research to find out what I need and where I need it. I've got probably one of the strongest slant 6 blocks that you can get coming to me(out of a 68 dodge truck, had more webbing and bracing then the car slants) But from this combo I can run almost 30 psi of boost and make over 1000 hp PROPERLY TUNED, which is why I will have the megasquirt that will enable me to tune it properly because I can monitor every aspect of the motor running and tune.
Good luck on what you decide to do but don't count out the lowly slant because one day I may coming flying by in my slant getting 20 mpg with as much hp as you :D hehe just teasing
btw 360scamp thats pretty sexy wanna show me some more pics?
