Re: Need motors head serial number decoded
Thanks, oh and the lb9 and L34 have different cams and heads dont they? Also so is what motor from 1983 is it called (l34 or what) thanks agin man.
Oh and im guesing a 1987 lb9 motor that has a edelbrock performer rpm intake, and holley 600 carb would be somwhere around the same hp and tq as a tpi setup maybe a little less rite?

Re: Need motors head serial number decoded
Ya, i saw the motor list for years, on there and on the camaro tech part of the forum, but that doesnt tell me which one it is, so does that code not say anything other then it's a 1983 305 carb motor? I really want to find out, thanks

Re: Need motors head serial number decoded
This isn't going to format properly but you can still see what it says. Looks to me like all the DDD code engines are LG-4 and never had EFI

Re: Need motors head serial number decoded
Ok, thanks i guess i just need to buy a lb9 motor and swap this crappy l34 out, or should i put a tpi setup onto it, or would the two make almost the exact same power?

Re: Need motors head serial number decoded
Why would you bother.
Just buy a 350 ; any 350 and have more Hp
Where do you keep getting that code from ?
It has already been explained for you that DDD block you have came from a LG4.
Of course you realize 30 years down the track there may be little of that original 305 engine left, best to check the head /cam numbers before sending everything to the bin

Re: Need motors head serial number decoded
the heads on the l34 motor say 14022601, and I think those came on these motors, so it seems like a stock motor but either way when it comes out i miht venture out and mess with it's internalls but probably has the stock cam still, but it oes seem like it has some power compared to my old 89 s10 that had a 350tpi motor in it with 3.73s in it i would say it feels slower top end wise but seems like maybe THE OLD L34 has aroun 260-270 tq if i had to guess

Re: Need motors head serial number decoded
Wiring required is no different on a Vortec to any other reg 350 ; it will depend what injection you choose to run
