I recently purchased a 383 Stroker motor and the block casting is 14093638 with a date code of G161. This is a 4 bolt block. Is this a good block for this type of motor. I was told it was a marine application originally. I am trying to sell this motor and a guy who has been asking for info told me he is going to pass because of the block. He said he went to a few forum sites and some say this is not a good performance build block. Does anyone have any info?
Thanks,
Bill

 

14093638...350...87-95...2 or 4...Roller or flat tappet cam, one-piece rear seal

not a crap block. it's not aluminum, which some "performance" guys want, but not a bad block to build. i know quite a few builders who would use this block over a 2 piece rear main seal block. sounds like this guy is looking for something more specific.

Hi ITSBACK,

Welcome to the Chevy Forums.

We are to assume, of course, that you purchased the engine with a specific purpose in mind. What is your intended usage? What kind of HP are you looking at on paper? It would help if we all knew the plan, so we aren't working in the dark.

IMO, (given the information you have provided) if you intend to use it to replace an L-block engine in an older vehicle, or you need it for workable horsepower for commercial applications, the stroker with 4 bolt mains is a great start.

Since the advent of the never Vortec engines , many factory engines have an inherent advantage in horsepower for which the older engines are hard-pressed to compensate.
For example, years ago, a 350 or 400 engine with over 300 horsepower used to take some work and money. Todays standard 6.0 Vortec engine exits the factory with 340HP+ stock.

 

Thanks for the input guys. As far as use for motor, I bought it to sell it, and help a friend going through some rough times since I had the cash. This motor was set up to be in the 450hp range. I actually have another guy interested at the moment who wants to swap his 5.7 to this motor in a 96 Impala SS, he just does not know if it is a direct swap or not. Does anyone know if this is a bolt in swap for this car?
Thanks,
Bill

 

the block will bolt in, but the heads and intake may be different. what are the casting numbers on the heads, or what kind of fuel induction is it? throttle body fuel injected, carb, other injection?
