It was just too lazy off idle. I like the throttle response with the blower better. However the torque from the turbo was ungodly.

....but turbos don't come online right off idle. Only positive displacement blowers do that.

I can't help but wonder what point there is in building a temporary 347 blower engine with giant heads when any decent boost is going to overpower the block anyway. In fact, why not just start building the 408 you want instead of doing everything twice? I wouldn't even bother supercharging it; you can get well over 450hp from a pump gas 408 if the parts are matched decently.

i want to learn how to build engines, i would much rather build a 1000 doller engine to play with and learn on then a 10,000 engine and blow it up because i dont know what im doing, Thats the only reason.

I am with speedfreak on this one.

I would build a 351w instead of a 302. That 302 will split down the middle with any amount of real power.

Not sure how streetable it would be NA and pushing 450 to the ground with a 302, but there is always N2O with a smaller cam to do the trick.

[Pimpdady753]

how much can a stock 302 block handle, i herd they can handle 500hp with a main gridle. I dont want more then 400hp, thats why the only thing im going to change is the heads to afr 185s, and the injectors. U get what im saying tho right, how i would rather learn how to bild a engine on a 1000 doller engine then the 408 i want to build that going to be like 10,000. I would much rather blow up the 347 then the 408. Thats what im thinking.

[SkylineUSA]

Main Girdle helps nothing, well it will help hold the rotating assemby together when the block splits.

500hp on borrowed time.

347, 185s, F303 and then your done, that is a lot more $1000 though. Your looking at $3k+ easy when your done, but its a good combo.

[Pimpdady753]

im not getting that cam, i have a cam aleady in th block, when i bought it they guy said there was a performance cam in it so ill just use that one. The heads i plan on using on the 408 when im done tinkering with the 347. I found a stroker kit for 700, and i called the shop buy me and they said they can clean, deck, and hone it for 200, the block was bord out the guy said.

[SkylineUSA]

What cam? Size? Lift , duration, lobe sep, timing evnts? Hyro, roller?

700 for stroker, don't push it too much, or ou might have a window in your block.

Heads $1500
Intake $300
MAF $300
Stroker $700
Clutch $300
New Trans $1000
ECU Management/Tune $800
headers $200
Etc, it adds up quick

[351wStang]

From experience, it all adds up. Just when you think you're done, you gotta get belts/fluids or something stupid like that. Then you do a final check over and see some more stuff, the list goes on. 400hp is not cheap. Its a hell of a lot cheaper than 750hp, believe me. But even 300hp isn't "cheap".

as the old saying goes speed costs money how fast do you want to go.

I agree completely. I started out to build a $3,500 375-400hp street car. I ended up building a $24,000 750hp 9 second drag radial car that was a PITA to drive on the street.
Now I drive a $10,000 475hp '69 Cougar. So far its been the most fun, and I built it in about 10 days instead of the 2 years it took to build the drag radial '87 mustang.
