Has anyone ever used a later model 350 engine? I had one given to me. It is just the short block and will need to be reworked. I believe it came out of a '91 or '92 chevy p/u. It has the one piece rear main seal. Before I go through all the machine work to build this motor, I was just wandering if there was any difference between it and a mid '80's and below. I cant use vortech heads either.

The bolt pattern on the crank is diff. for the flywheel. Other than that I'm pretty sure everything else will work. Just run a flywheel for that year model.

Mine is fine so's .030.Get the vortec's redrilled and they will look like the heads that came on it unless they check the casting #'s.

Something that no one is mentioning is that the later model blocks do not have fuel pump rods or nor is is it drilled! If you can not run an electric fuel pump it may not work for you.
I am running one out of a 1992 Chev PU 350 stock bore with a little hydraulic cm and turn it 5800-5900 every Saturday night with no problems so far.

Some blocks are drilled up to about 93 or 94 these are all truck blocks as far as I know. Hope this may help. As mentioned before use the correct balancer and flywheel and you wont have any problems. Oh by the way have a lo9cal machine shop check the rods and rod bolts I have personally had a problem with the powdered rods.

What problem did you have with the powder rods, I thought they were better than old style stock rods.

Thanks for all the advice. I got to checking and it didnt have the rod or hole drilled for the fuel pump rod. We have to run mechanical pumps only. So, dont know what it supposedly came out of. But I know what it isnt going in...LOL. It was free to me, and it was also free to the next person that came along. Plus it did need a ton of machine work. Thanks. Y'all saved me from unneeded money seperation.

It's a draw on which block you will get,some up to 96' will have everything there for a pump and some all the way bach to the early 90's won't,my 89' has it drilled.
