i think this intake i have might be worth something , its been in the family for years the casting# is 3959594 and it is aluminum and has the firing order on the front and it is a spreadbore pattern , thanks

It's a ' 71-72 LT-1 intake. Want to sell it?

well the date code is september 1970 so its most likely a 71 model LT1 intake , it is in beautiful shape too no stripped holes or anything , thanks for the help , mark

And the engine in your shed may be the LT-1 engine that the manifold came on, it sounds like it has all the right parts.

the bitterness of poor quality remains, long after the sweetness of the low price is forgotten

what is the true way to tell that that block is an LT 1? all the numbers on the front arent cast the same as on my other blocks and
i also wanted to ask if the part numbers on the caps are useful in any way? it just tells me from looking that they are a matching set but thats about it , thanks , mark

Is it a four bolt main block?

No, its a 2 bolt main block, were all LT-1's four bolt mains? If so, this one isn't, thanks, Mark.

CMR is not a LT1 engine. See other post for info on CMR.
