duh.. stock bore/stroke.. lol good reasoning, but if you ever build a stroker, i strongly recommend a custom grind.. OTS cams really suck in a boosted stroker.. i went through 5 cams before calling cam innovations.. unfortunately, it appears he's no longer making cams :(

Yeah a custom grind is always a good idea. The Fcam will work for now.

Thanks,

Give Ed Curtis a call at FTI.. $325 for custom cam, sell you f cam. For the extra ~$200 your combo will have more power and better drivability. Its going to pull the whole combo together IMHO.

Hmm. It's a possibility. One of my many hurdles is that my fuel system this year will only do 600 rwhp.
Stock fuel lines! Just no budget this year for the big fuel system. I can probably make 550rwhp on 12psi
On stock stuff. So wasn't really needing the cam to wow me.

I understand now, I really didn't know too much about F cams and turbos to be honest with you, sorry for jumping the gun with my custom comment :) It's a whole different world with turbo applications that I wasn't aware of

I hear ya Bob. With a turbo you dont have to have the perfect intake air flow to make good power.

The GT40 lightning heads are at the machine shop getting checked out. If all goes well the engine should be installed mid March.

what size turbo are you using just wondering wanting to compare my setup vs yours lol. I have a staock 302 botem end and a f303 cam, it also has trick flow twisted wedge heads 170s but they have been ported dont know how big they are. Also i have blowthrough setup instead of efi so you got me there lol.

I have a cheap 75mm with 1.00 ration exhaust housing. Blow through carb is a great way to use a turbo setup. Im a computer guy, so I like the EFI stuff. Your biggest hurdle besides tuning is the failure rate of the 5.0. People break the block with stock heads and cams. So with your upgraded heads and cam, you will just make more power on less boost. If you keep it to 450rwhp, it should last.....should.... :)

That is why I stepped up to the 351. Yeah more cost up front, but the engine will stay together.

You know a 351w max hp rating isn't a whole lot more then a 302 right? Maybe 50-75 hp depending on what year the engine is.

PS I hope you are saying the Stock 351W block will make 750-800 REAR wheel HP??

The 1974 Windsor block in my turbo car broke @ 675 @ the rear tires
