to rebuild or order a short block
my block cracked now to decide to get a crate short block or rebuild another block.

My spare still sits in the 72 chevy pickup it came with. The rings are bad enough it got parked so definitly have to bore. Can't remember the casting number but it is an unopened 350 with a 1 or 2 barrel carb. I think it is a 1 barrel. Carb is the size if my fist. 2 bolt main. I haven't decide about transferring the 327 large journal crank. I need new pistons. the old ones are way too much compression for me(11.5). Getting a new cam either way.

This will be a daily driver with vortec heads around 9.5 c/r. Shooting for around 375hp. Which would be cheaper? I have seen short blocks for under a grand, but not sure if they are worth it.

I recommend Blaine's Engines out of Dallas... I am running one of their race engine...

Believe it or not a short block $485.00 Heads set up and ready to go $330.00

Really nice work Call Sean and tell him Fred sent you.

Whether you rebuild or buy a crate motor, you really need to be careful. Crate motors are the easiest way to go and several machine shops will even build the engine they way you want. $1000 for a complete motor sounds like the local auto parts small block offer. I've heard some strange to nightmare stories about those and I'd be cautious on dropping the money for a piece of junk motor. Another option is assemble it yourself and find a great local machine shop that will do all the machining for your. I would ask some local hotrodders in your area.

Be aware that the label, "rebuilt" or "remanufactured" means different thing to different shops.

If you see a shortblock for <$500.00, does it have used pistons in a honed bore? If not, I don't see how the shop could afford to bore and install fresh pistons/rings, turn the crank, install bearings, etc. and still turn a profit.

You can take a chance on a junkyard engine that's in running condition, hit up craigslist, shop the machine shops in your area for engines that weren't picked up (and price the rebuilding of your old engine while you are there), shop the newspaper classifieds, look for a running vehicle w/a 350 in it for cheap- the options are many and varied.

BTW- A '72 350 truck will have at least a 2-bbl. on it.

Blaine's uses all NEW parts except the block...

All work done on CNC hence the low cost

Purchased a GM 350 290 HP crate motor brand new from GM have had nothing but problems (overheating) with it and ran into a gent at the York street rod show having the same problem. The problem we both have is getting answers to questions no tech line available - only e-mails saying never head of that before. I am sure I will work the problem out now that I have found someone else with the same problem.

The point....Cheap does not always work.
Look for local shops and ask for recommendations if there are any
good, they will give them out ,Then call them and ask if the had
problems. After I got the crate motor my local auto parts told
me about a local re builder 1 mile from me $1,000.00 including
heads, all new parts They supplied used block. 40 years in
Business does not advertise other the word of mouth and does
have problems. Boy did I make a mistake....Jim
