just curious, Ive been searching for a good motor/trans for my street/strip Monte...i just bought a donor Monte that came with a truck 305, th350 trans, and 7.5 rear with 411 gears, Im probably putting the TH350 trans and 411 rear in my Monte and selling the rest of the donor car. I might be able to get a great deal on a MINT 91ish 2wd Chevy stepside pickup with a stock 350 and im assuming a 700r4 trans with 125k mileage blown rear for $800 "I could sell it as a roller for the price I paid for the whole truck". Just an example of what Im looking at. Just looking for a good motor to add a cam, intake, carb, and headers. I dont care about gas mileage just looking for a budget build, I know the LT1 is a popular choice but what else it out there, which GM vehicles are hiding potential under the hood for a driveway budget builder?...and what year's should I be looking for?...also is there any stock GM motors that will handle a 100-150 shot of spray "nicely"?

96-99 Trucks with L31 Vortec 350 are a good donor, Came with factory Roller Cam & Vortec Heads.
Stock engine in good shape will handle that level of N2o.

Might get lucky and find one of the f-bods with the L98 in it or even newer cars with the LSx type motors are showing up in junkyards now. Can get a good deal on one of them someplace that charges based on how many cylinders the motor is rather than what it came out of.

I paid $400 for a 350 with a Moroso oil pan,M/T valve covers,1.5 roller rockers/Edelbrock Torker 2 intake,Edelbrock carb and some headers at the junkyard.The motor was dirty but the guy let me hear it run before he pulled it out I just painted the motor with Engine Enamel and change the pulleys and it looks nice now

You should check around on Craigslist also. There's some good deals that pop up on there sometimes.

What small block is good? If you want a gen 1 block, 70's through early 90's. Look for a truck block with 5.7L stamped on it. Then look for 010 stamped in the rear area of that 5.7L block. The 010 means it's a high perf or heavy duty designated block, high nickel, 4-bolt main.

I got one out of '86 3/4 ton Suburban 4x4.

.. For real budget power, check around for a '70 - '80 SBC 400"... or keep an eye out for old cars in people's yards... especially out in the countryside... buy it, strip out the drivetrain, and part out/scrap out the rest...

My 010 block is a two bolt 350 so don't assume all 010 blocks are four bolts. It's OK though because you can install splayed caps and it be stronger than a factory four bolt.

even a 2bolt would be fine for your application, sure a 4bolt is great, but you say only a cam, intake, carb and headers. 2bolts are good for about 500hp than things can get hairy quick. With only those bolt-ons you wouldnt see much past 450hp anyways.

don't really dwell on if its a 2 or 4 bolt. but if you could find a high nickel block than that it awesome, but if not any 350 from early 70s to late 80's cars or trucks would do the trick
