they seem fairly good priced especially the ones that are a crate engine. HOWEVER, they are all carbed... i cant find a tpi engine on ebay?!!?

So, i have 2 questions.

1) if i put a carbed 350 in place of my 305 tpi. can i make the 350 into a tpi? can the tpi sensors be mounted on a 350 carbed block?


2) IF i stick with a carbed 350 crate motor, i guess i simply dont hook up the engine/computer wires BUT What happens with the auto tranny? how does one go about that?


thanks

eBay doesn't "sell" engines. eBay sells ad space.

PEOPLE sell engines on eBay.

it's not reasonable or sensible to lump every engine vendor on eBay into either being terrific, or being crap. You're dealing with an individual that just uses eBay as their "store", just like somebody advertising in the Yellow pages or the newspaper or the classifieds on this site. You wouldn't think, just because somebody is in the Yellow pages, their engines must be great (or not); same for eBay. You gotta look at the individual.

TPI is just an intake. The motor does not care whether you bolt up that to it, or a Super Victor, or a TBI, or a 74 Impala 2-barrel intake. They all bolt up. Subject of course to the 86-back vs 87-up intake bolt hole changeover, which isn't "TPI" specific.

Whatever engine you buy, you'd want to specify a cam that's appropriate to TPI. No matter what engine you buy, you'd either put the cam of your choice in it, or tell them what you want; so that's not anything out of the ordinary. A TPI-friendly cam in a 350 would be in the 215° @ .050" neighborhood on the intake, a little more than that on the exhaust side, and on 112° to 114° lobe separation. There's plenty of cams like that available so it shouldn't present a problem.

Yes all blocks have all holes for mounting sensors. That's not an issue.

I'd suggest that if your car has TPI, you should stick with it. Not that it's such a great system or anything like that, but there's ALOT worse out there too. Mostly, it's one less group of variables to try to sort out in the middle of a project.

 

the only thing you might run into for mounting things is you might have to drill a bolt boss or two in the heads for the serp set up. Otherwise they all have the same holes in the block(s) in the same spots.

Somebody who operates on eBay: 1987-1992 CHEVY 350 / 5.7 ENGINE - CHEVY ENGINES 87-92

My brother got one from them. Make sure you add the core & shipping charges to the price.

Your TPI will bolt right up to it (assuming you don't have an '85 or '86 TPI).

 

I bought my 347 Shortblock from Ebay and i haven't had any problems whatsoever.
