So what im thinking:

Build up another 305 using the master rebuild kit that i can get from motorville. The kit includes everything that i need to put a motor back together. I get to choose my pistons, cam, lifters, maybe some others. I'm thinking about using flat top pistons with an RV style camshaft. Good idea?

Pull my motor, have the heads machined and polished, slam them on the new motor, use my existing TBI. Maybe some bigger injectors? Rechip? what?

Use my 700R4 transmission, I'll pull it and put some performer stuff in it when i do the motor since i'll have to have it out anyways.

So from this the build cost looks like this:
Block: Freebie (girlfriend's dad has one with a fresh bore)
Master Rebuild kit: $159.99
Machining on the heads: Estimating $100
Bigger injectors: ?
New Chip: ?
Service trans: Freebie (Girlfriend's dad owns trans shop)
Wheel Base shortening: Freebie (Guy owes girlfriend's dad a
favor)
Paint: $500-$1000
FULL Interior: $500 (neighbor is an interior man)
Body work: Freebie (do need to provide materials)
New SWB: Not totally sure yet

total minumum cost: at least $1060, to redo my whole truck i think thats a Really good deal. Lemme know what you guys think.

Could you also post a LINK to a turbo/supercharger/blower that will fit a 5.0L 305 V8 in a Chevy truck?
