Thread: Engine Id

Tweet

I need help ID'in this engine, THE engine code is V1129CHX, also it has 010 in about 4 places. The heads castings are 333882. I was told it was out of a chevelle. The CASTING is GM 3970010. I want to put it in a 88 transam. I don't knopw If I can or if the engineit is worth the trouble. I could just as easily rebuild the 305 in the transam....help me please!!!

3970010 was a 2 or 4 bolt main block that came as either a 302, 327, or 350. HP ranged from 150-375. 33882 heads were the most common heads produced during the pollution controlled 70's. They have 76cc combustion chambers and 1.94/1.5 valves. The are prone to cracking. So, you've probably got a 150-165hp ls9 350 (GM rates them at 260 now). Nothing special, but it still has a little torque to it.

The 010 are cast in on both sides of the block.

Well Boss I have the same engine and it is a common block. As 76gmc1500 said 302 327 & 350. They came in a lot of cars. Mine is a 350 from a 74 impala. Again the heads are a 76cc 202 int 196 exh. but not too bad. they are said to be one of the best of the larger combustion chamber heads. As for the 010 on the block if it is cast in thats a good thing, it meen that you have 1% more nickle in the casting to prevent cracking. You may also discover that it has a 020 casting which represents 2% tin added for the same purpose. Either way it is a more desirable block and I have had little to no mechanical problems with mine. Change to an Edlebrock Performer intake with a 600 cfm 1405 Edle carb, add a big K&N filter and maybe even some headers. For about $500 at Summit you'll love it. Drop it in that TA like that and I bet you run around 13.6 in a quarter. Slower than some but faster than most. That's my advice anyway

.........the heads are a 76cc 202 int 196 exh........said to be one of the best of the larger combustion chamber heads.


Anybody besides me think that would have to be an awful large cumbustion chamber to hold those valves

sorry about that guys... must have been half asleep
