Plus, you can always bore the block, slap in 5.7L pistons, and some aluminum heads, which would be sweet. All I would like would be the 4.3L crank for the smaller stroke to acheive more RPMs. To regain some cubes, just get .060 over pistons.

I have never seen a LT1 4-bolt other than the Vette Motors. If it is a 4-bolt in the 4.3, then go for it. I am not sayin that it's not possible, just never saw one, and we have taken a few apart.

"265 - There was only one block used for the 265 cid version of the LT1. It’s a 10168588 casting that had the numbers "4.3" cast on the side, too. It’s real easy to spot if the heads are off because of the small 3.74" bore. Getting the right cam in the right engine can be a little bit tricky because there were several variations over the years. There are essentially two different grinds used with two different snouts, depending on which distributor was used on the engine."

I'm 80% sure they mean there wasn't a 2bolt Main version, an Aluminum block version, or like a modified GenI SBC used. It was just the ONE 4Bolt main block. They could mean it was a standalone block, but a HIGHLY doubt it.

By that logic, a 4-bolt Mopar engine has a vette block.

Good luck with that .264" overbore.


Where did the 4-bolt L99 info come from, anyway? That would be really silly of GM to go 4-bolt on that engine...

The 265 had single exhaust in the cop caprices, (the were more civilian type cars). The LT1 got duals to my knowledge (pursuit type).

Correct. In exactly the same way that it is completely illogical to call an L99 block a "vette block."

I did read the thread. There is nothing in the thread that says L99's have 4-bolt blocks, until you started talking about it out of the blue.


In fact, there's nothing linked from the thread that says it has a 4-bolt, either:

http://www.akmcables.com/l99.htm From our very own Camaroholic.
On that page he says his warranty-replacement LT1 engine had 4-bolts.

Doesn't say anything about the type of caps on the L99.


well if you guys would read the thread lol
Well, if you would learn some reading comprehension, lol.

Ah, well then yes, once you mention he's talking about his old 350 LT1 and not the old L99, it makes sense lol

My appologies.

I'd still like to get the crank and punch the 5.7 LT1 .060 over to make up some lost cubes
