throttle body fuel injected V-8 350 chevy.It is in a 1990 Chevy van


i have a 1990 rs with a 3.1 will that engine fit in mine?????

 

Yes but its gonna be a long journey for that. I would HIGHLY recomend some supension upgrades and some other reinforcments. Is it a TBI injection?

 

'90 Chevy van 350 would be LO5 TBI.

It's basically a V6 to V8 swap. See sticky above (if you haven't already). Your current transmission won't work, and the van tranny will need modification.

 

thanks guys, i'll just find another engine, i appreaciate the help

 

Hmmm, how'd we scare you off with what we said?

 

not really scared off, just want to use the 700r4 iin the car already, no room in budget to buy a tranny, i saw that engine on ebay and thought it might work, so if i bought that i would have to find a tranny to work with it as well, more work thank i want to do, my goal is not to build a hot rod or anything, just want a simple swap to 305 or 350 for a little more power, atleast i hope simple, my understanding is , a 90-92 v8 with wire harness ecm computer, new motor mounts , fuel pump, and front springs and i am in business. atleast i hope it goes that easy

 

There isn't any V8 that your transmission would work on. The van engine is as good as any other in that respect. If you could get the transmission from the van as well, a simple tailshaft housing swap from your current tranny would be all that is required to get the van tranny to work in the RS. Otherwise, the parts you listed, along with little things like throttle cables and hoses, will get you there.

Have you checked the classifieds on this Board? People doing LS1 swaps would have the drivetrain stuff you'd need.

 

really? i thought the 700r4 would bolt right up to a 305 or 350? sorry if i seem ignorant on the subject, a friend of mine sold me this 90rs with 3.1 and 700r4 for a mere 300 bucks, and i have had it for only 2 months or so, and this is my new hobby now, so i do not know alot about these cars ....yet

 

The 3.1l engine has a 60 degree bellhousing. All 305,350,383 etc. have a 90 degree bellhousing. I have heard rumors of an adapter plate to convert to sbc, but as of yet, I haven't found one.

 

can i just change to a 90 degree bell housing?or do i just need to get another 700r4 from a v8 car?

 

the bellhousing's are not removeable...all one piece. Yes you would need one from a v8 car.

 

Or van.

The 4.3l V6 has the same bellhousing pattern as Chevy V8's. (That info is in the V6 to V8 swap sticky.)
