sleeper88

hey guys the time is coming soon for me to start modding my 88 5 liter hatch. now my main concern is reliability , i want the car to start up with minimum hassle and breakdowns. my goal is 500 horsepower and 500 pounds of torque, to the crank NOT the wheel.

i have 2 set ups in mind and since i can trust you guys to give me the right advice and all i wouldnt mind having some help. and keep in mind the motor will be rebuilt to a 306 and im planning on using the stock block, tranny and rear end.

set up 1. 331 stroker (ive heard from numerous sources that the 347 is a oil drinker,,please let me know if thats right because i would obsviously go with the 347 for more cubes) afr 185 heads, ported lower cobra intake , 1.7 roller rockers and a custom cam.

set up 2. vortech blower 8 to 10 psi. ported lower cobra intake , afr 185 heads, mild cam.

any help, input or suggestions to these setups will be greatly appreciated!

I'm a little confused, is 'set up 2' a blower on your stock 306 block or on the stoker motor? I don't think a 347 stroker will make 500hp unless you supercharge it but I may be wrong.

I also heard numerous times that a 331 will out-live a 347, somewhere in a mustang magazine they mentioned the 331 had better rod ratios or something...??

For good reliabilty I'd think the 331 w/ a blower with a good tune should be alright. The 306 with a blower will probably be a little more street worthy. Your stock transmission won't last though if you poweshift at all.

you can buy 500hp racing 347's from cobra automotive......but it would be carburated and it would cost a pretty penny
