hi guys new to the forum and wondering if someone here could help me out. i have a 60 impala with a 235 i6. gonna drop a small block in. i know the bellhousing is different so im going with a short turbo 350 to replace the ironglide. i guess my question is what motor mounts should i use? i have all kinds of parts so im not going to go aftermarket. chevy pickup? car? what year is the best to use for my car? i have stuff from 283 to vortec. but nothing x frame with a v8 to look at. i just finished pulling the six out about an hour ago so havent mocked anything up yet but maybe some suggestions could save some messing around. thanks for any help!!
also, exhaust suggestions? cant find much for headers other then super comps but on a budget so thats out the window. but block hugger headers? or should i just go with ram horns? i think i have a set of the old vet big tube ram horns from my stock car days. but block huggers might look pretty good so what works? thanks again
Throwing in a 1968-1986 350 just might be what the old car needs.
If changing from powerglide to th350.. measure the exact length of each tranny. There is more than likely going to be a difference.
I bet the original differential gear ratio was low for that 235 to pull a hill strong enough. So plan on changing that too unless you don't mind 3,000 rpms and 12 mpg on the 350 engine at 60 mph.
Seems most these guys would go with a 700r4 overdrive to match that lower gear ratio.. to acheive 18-20 mpg.
If the frame crossmembers do not unbolt to be moved fore and aft.. they will need the cutting torch and welding treatment.. to get them in position for engine mounts and transmission mounts.
its a 383 vortec. one peice rear seal. 4 bolt mains. rh dipstick. mockup went great today. the car came factory with sbc mounts, it just had adapter plates for the six. bolted up the mock motor no prob. drilled new holes in the cross member for the th350. used a driveshaft from a 3 speed car (shorter shaft). so now i just need a new steady bearing and some headers and ill be ready to roll! thanks

my car has 3.31 gears with 28 inch tires so im just under 2500 rpm at highway speed. all 700s are long shaft and dont like abuse without mods. 400 + hp in a HEAVY car lol going to the grocery store might be abuse.
Napa lists it, but you don't have a counter person willing to check the books. Hate those guys but, it happens at larger stores.
