Hi guys, Another question on the 66 C20 that I'm converting to a V-8.
You are saying that I can just take the flywheel off the I6 engine and bolt it on the 350 smallblock?? Then keep everything else the same??
Will the original bell housing bolt up to the 350??
Thanks guys. Huge help.

The V8 and six flywheel will swap.

You can reuse the flywheel, starter, clutch, pressure plate, all of that on the V8 too. The bellhousing is the same pattern too.

I've done this swap plenty of times in the past, back when I was younger and foolish. I'm addicted to inline engines now, so I wouldn't ever think of doing it anymore.

You need to poke your head in over at the www.67-72chevytrucks.com board. Don't let the name fool you, we talk all years of trucks. I'm a moderator and post whore over there. We'd be happy to have you.

I've personally done it, works as long as the six is not a 292 & the V8 is not a 400, anything else goes. I love Chevy for that reason, many parts swap. Brian

You'll need a clutch pivot ball to screw into the V8 block. The I6 one is different and won't interchange.

Thanks for the help. Now I'll be on my way....I hope.

Sorry I didn't get back to ya yesterday. It was a little hectic.

Yes, we're basically sayin that you can do just that. The I6 and V8 bellhousing patterns are the same (until ya get into later years...and then it becomes a mess.) Bearing in mind some of the things that other folks have suggested, I think you should be in for a pretty simple swap.

The best way to find out is to start turnin wrenches. A word of suggestion: if you haven't done this before, label the wires, hoses, etc. that you remove....and use waterproof ink, just in case you end up washing down the engine compartment before droppin the V8 in. This will make reconnection a lot easier. There shouldn't be a whole lotta stuff to connect (wanna help with my 85 Monte Carlo? It's like rewiring the phone company's connections) so it really otta go pretty smooth.

Good luck with it.

No problem ChevAssylum. There's plenty of people who lend their advice.
Yea when I bought the pickup the guy had just pulled the 6 banger but left the tranny in. Slapping in the V-8 shouldn't be a problem. I've done a small number of engine swaps, slow & steady wins the race.
Thanks again.

I hereby nominate you experts to write a tech article on this business.
