Allright im starting to break down. i have a 305 tbi in my 95 Chevy/Gmc reg. cab 5 speed. i wanna drop a 350 in it, what all do i need?

 

[98_k1500]

TBI 350 engine, 350 PROM. or a vortec 350, carb intake, TBI adapter, and tune if you want some more ponies.

What can i convert over from my 305? like if i buy a base engine?

 

[98_k1500]

Depends on what you mean by a base engine. Need more details.

Like if the engine is just the engine, no water pump, cap, them kinda things. will i be able to put my tbi from my 305 onto the 350? the engine mounts should all be the same, and will it slide right into my tranny?

 

[98_k1500]

Yes, everything off a 305 should be a direct fit to a 350, same engine block. You can use your intake, tb, dist., flywheel, and all your accessories. Your trans will bolt to it. If you go back with a tbi engine, all you will need is a PROM chip for a 350.

I know the knock sensors are different for a 350/305, and they are also different for a manual/auto truck. No idea why, but you will need one of these.

allright, well this engine im buying for like $200, is missing two pistons because the guy took them out to put in a different rebuild. how would i go about fixing this? i wanna put all new spark plugs in it, what would you suggest? What brands is best to look for?

 

[98_k1500]

Little more info needed here, if the engine is already torn down, I would def. recommend a complete rebuild. I run ac delco plugs, they are rated to last 100,000 miles.

The only problem its not cheap, and im not sure what parts to get for it.
