Just do the supercharger. you can easily get into the power range to crack a stock 302 block with a basic vortech kit and gt40 iron heads and an explorer intake. so why plunk down a bunch of money on aluminum heads/intake/cam. a basic vortech kit with proper injectors and fuel supply will make 360whp properly tuned on a stock 5.0. You can expect anywhere from 280-340whp with a well selected set of heads/intake/cam. But if you go with a stroker later 347 later on you may find the 165-185cc heads you put on with your naturally aspirated 302 are now too small. Food for thought. Feel free to send me a pm, i live in the seattle area and know these 5.0HO motors well. A friend of mine has his own shop on Vashon and has a 410ci windsor with a Vortech YSI while I have a 302 with a Paxton Novi 2000, i'm sure we can get you hooked up in the right direction, been messing with sbf's for quite awhile. you basically need to tap the
oil pan for the
oil return line from the head unit since you are feeding it
oil from your oil pressure sending post, change injectors, upgrade your fuel pump and have the ECU/MAF tuned/recalibrated and a few other things related to the PCV system if you want to do it right. Most kits come with bandaid items like booster pumps, FMU's in increase fuel pressure to use stock injectors etc etc. they can work, but if you just do it right you will be more happy in the longrun.
