Help me i.d. this engine

[saxart]

I'm hoping someone here can help me I.D. this engine. Bought this truck three weeks ago and the previous owner said the engine was replaced with one out of a 1974 GM vehicle. (He can't remember) I've tried to look it up on the interweb, but keep getting conflicting information.

Is the engine a 350, or some other size?

(Thanks in advance!)



"TO416CMA"



"14L196828"



Here is the carb numbers if they help with ID also...

You've probably been here -- the A in CMA does not match but the L in the eng vin looks like a 350.

Can you get a couple of good pics of the harmonic balancer? That might help with identification. I can tell the 350 and 305 apart using the harmonic balancer but I'm not that familiar with the 283 or 400.

Thanks a lot Bruceman, that's exactly the info I was looking for..

The main reason is that I'm in need of a new set of headers, and full exhaust

This is a budget build, so if anybody has recommendations for either headers or exhaust that won't break the bank, please post!

If your cast iron exhaust manifolds are intact I'd surely use them.

unless you are going to fork out big bucks scrap the header idea. inexpensive headers are a source for leaks and unless you have the "motor" that needs them they are a waste of money. if your manifolds are not cracked just resurface them and bolt them back on-WITHOUT gaskets. as long as the head surface is clean and straight you won't have any leaks. before i get trashed for my comment-i work in a muffler shop (31+ years) and thats how we have always done them.

Sounds like you got it figured out.
For everyone's future reference, I found this link to be helpful for figuring out all kinds of Chevy casting numbers. Cranks, heads, blocks, intake and exhaust manifolds, etc.

Thanks for this thought. Yes, after doing some research here on the site, it sounds like I'll be staying with the original ram-horn cast manifolds.

This brings up another question... The outlet on these manifolds point straight down (as opposed to curving toward the back) Are those the correct manifolds for a 2WD truck? I may be getting the LMC exhaust and want to make sure we don't have to send it back.

Thanks again for the help.

TeamEstep-
That site it great!

on a 2wd they should both curve back. if your truck has the engine in the stock location for a 2wd V-8 you need to find the correct manifolds otherwise the LMC kit won't fit. i've done duals on 2wd trucks with the straight dump manifolds and it is a pain in the a$$ - tight bends and difficult (damn near impossible) to tighten the nuts onto the studs. just post a "want to buy" thread on the parts board and someone here will help you out with the correct manifolds.
