all right guys i need a little help and advise. i have a 94 gt that is getting a 351 put in it. now i got the motor from a 91 f350 pickup for free and im going to have a shop rebuild the bottom end. now my question would be what combo of internals, heads, fuel injectors. i all ready decided to run a efi spyder upper and lowerintake. but id like to see around 400 to 450 hp on motor and tuning alone. then eventually put a supercharger on it for the 550 to 600 range.

so my main question is what would you guys recomend me using to achive my hp goals.

 

The efi spyder intake is a high rpm or forserious superchargedapplications. It needs lots of rpms. You'll need good heads and astrong bottom end. If this i going to be a treet car you'll want to go with a TFS street or even a track heat intake. Remember with a supercharged motor a set of 42 lb injectors are really only good to about 540 rwhp. Then they end up have to work at over 100%. To see 400 hp on motor you'll need a good set of heads. TFS street heats or afr 205' or 225's that have been ported.
