Free sb400.... Is it worth it?

[jaredmajor]

I picked up a disassembeled sb400 for free. It's been bored .030 over already, has 76cc heads, stock cast intake, q-jet that definitley needs rebuilding, and some other crap. Is it worth even rebuilding? If i did it would be bored .040 over. I already have a good running rebuilt 355 in my truck. Would this engine out last the time and money spent rebuilding it?

400sbc is the **** as long as it will clean up at .040 I'd say go for it 6.00 rods and a good crank and a set of good aftermarket heads or vortec heads and you'll have a badass truck motor I love both of my 400 based engines

i doubt i would even have heating problems like i hear plague the 400. I have a hard time keeping my 355 up to operating temp as it is.

Mines .040 over and I don't even run a shroud on my fan I've yet to see 180 degrees even down here where the temps get up 110's

what about all of this cracking that i hear to the block and the heads? Is it mainly the heads that crack?

 

[jaredmajor]

I have 76cc heads on my 350, would those work, or do they have the "steam holes" or what ever they are?

Any 350 heads will work in a SB400 AS LONG as the steam holes have been machined into them. You have to have the steam holes in the heads.
