The 350 290 HP engine is an LM1 with a L82 cam . Its a good engine and a 4 bolt main . But it lacks compression its 8.5to1 . Best thing to do is change the heads first . The cam is OK for now . Its a 222 dur at .050 and 450in/460ex lift . This cam will respond well to the higher compression . Some guys will say go with the Vortec heads . You do need a cylinder head that is 64cc that should give you around 9.5 to1 with your stock deck block . For an intake manifold you will need to first pick the heads . The Vortec heads do work well but you will need different valve covers and rocker arms . I still am not very fond of the vortec heads . In there stock form they have pressed in rocker studs and limited to around 470 lift . But they will work out of the box on your engine with your cam . And give you about 40HP . COOL

the cam that is in their is nice. runs well and has a little bit of cakle at idle which is cool. goes pretty good for a 3500 pound car IMO

i guess i can introduce myself while im here, i drive a 1983 cutlass supreme w/ a 350 chevy crate 290/305 (the topic of this thread) i have an msd hei distibutor kit w/8.5mm wires,flowtech ceramic coated longtube headers into Pypes 2.5" Xpipe exhaust. The car has a 700R4 4 spd overdrive trans with a shift kit. the rear is out of an 86 442 cutlass. it is a 8.5" limited slip rear w/ 3/73s.

later

You are very lucky to have the 8.5 rearend,especially out of an 86 442 as they are rare cars,these are way stronger than the 7.5 these cars come with.

yeah they are hard to come by...got it for free too! hehe
one of my dads customers (owns an auto repair shop) left the car at the shop for 4 years, couldnt get a hold of him, couldnt get a title,nothin. so we decided to strip it apart lol. it was a nice car too, oh man. it was blue,grey and gold. t-tops,dual exhaust,blue buckets. didnt have the 9code 307, just a blown buick 307. still wish we couldve gotten the title oh well. now i have a cutlass supreme 442 Lol
here are some pics

Is your AC still working ?? If not,you can get rid of some stuff under the hood & clean it up a bit.Heres what mine looks like.
