The 327 would be a better choice for a turbo app. The bore/stroke on the 327 has a lot less side-loading, plus, the stroke is so short you can rev 'em pretty hard without tossing a rod. It's pretty hard to toss a rod out of a 350 also, but the 327 is just hard core. If you're gonna go all top-end balls out power with no real desire to street, do the 327. I had a high duration, low lift cam in my '65 327 and it was laying down a solid 350hp and taching out to 7,000 RPM all day.

If those 327 heads need valve seals and springs, you should just invest the $150 at Clearwater Cylinder Head for a trade-out on those heads for some fresh ones. Best case scenario they're 1.94/1.50 heads, so it's not like you need to worry about losing something valuable. It'll save you time and energy, plus, you'll have new, tight heads. While you've got 'em off, do the lifters, the head gaskets, and any other gaskets that engine needs. A FelPro gasket kit for an SBC costs about $40 at Discount.

Seriously though, if I were you, I'd take the 327 out of the car for the weekend, drop the heads off, clean and paint that engine bay, toss the $40 gasket kit in the engine, and degrease that block before tossing it back in. It'll look like a million bucks. As long as the rings are good, a new set of gaskets'll have that thing running like brand new.

With that 350, I hope you had those Vortec heads worked. Stock, contrary to popular belief, they flow kinda like shit for any high performance applications. They'll make one hell of a torque monster, but at high RPM/high lift, they kinda lose their flare. Sounds like they might be good for a forced induction setup though, especially with a milder cam for the turbo.

Blah blah blah, preach preach preach, if you need any help, let me know. I'm pretty handy on old 60's Chevy engines.

 

My whole family has had bad experiences at CCH so we are pretty disappointed with them. The 327 needs rings badly, the blow-by is horrible. I might buy the 327 from my dad and get a project Nova or Chevelle for myself, see as i have awhile until i can drive about 1 1/2 years lol. I dunno we'll see as time goes on how things lay them selves out

 

hey if your 327 is a 4 bolt i and u want to sell it hit me up bro.

 

It's a 1964 327 out of a Chevelle SS, you tell me if it is a 2-bolt or a 4-bolt

 

All 327's are two-bolt mains.

 

the 3970010 block in 1969 u could get it 2 bolt or 4 bolt and was used for 302,327 and 350s and some 4 bolt 327 where made.

but look on the back right of the block and u should see a block number.that has a small rod journal crank in it.so it uses 2.00 main instead of 2.10

how much do u want for it.i got racing stuff that we can maybe trade for it or cash

 

Damn, I just got told. Tony knows his shit.

Edit - I've got a 2 bolt '65 327 bottom end. I might trade it for something worthwhile. It's .020" over and I've got the small journal forged crank, rods, and a set of Sterling pistons.

 

what are u looking for?right now i just got a complete dart racing top end but i think i got that sold already.

next i'm going to get a ship ment of bryant billet race cranks in.going to sell them for around 750$ each.

does that 65 block have the 2.30 crank mains or the std 2.45 350 main style.

 

Couldn't tell ya. You're welcome to come by and take a look at it. It's all sitting in my garage.

 

just give me the number on the crank snout and the block and i can look it up.
