Confused Gotta 1950 i want to 350 its ass. Therefore i dont have computer hardware needed for sensors and such. Can i just put a roller cam and lifters with comp heads on an older block with a qjet carb and get away with it? What years block would allow for this? Just want a street highway machine roughly 400 horse.  Thanks  Stan

Try and find an old 4 bolt main block.,. the last 3 numbers at the rear of the block are 010.,. start your build there.

+1 Tuff

The old iron can't be beat. I just want to add what Tuff said about the numbers. they are (2) numbers that are good building blocks. .010 is 1% more tin, and .020 is 2% more nickel. These numbers can be found under the timing chain cover. Those blocks are hard too find and the guys that know what they have want *** for them. Your 1950's block is a small journal. I wouldn't want to make any real horse power with that block...

Hi there you ols Blokes,
I had an 010 with 2 bolt mails rebuilt
with grade 8 bolts every where with fully
balanced assembly. [I watched the engineer
balance the motor properly.] As he said..
" This way the crankshaft does not swing AFTER
the Bell."  For what you need the 2 bolt dressed
properly will do up to 350 Horses..
All the best to all you guys.

 I must be older then you. Like you said dress the older 2 bolt block up with ARP stuff. We have put 500 horse power on those old blocks and 400 runs before you need to freshen them. The old Iron is a great start for anyone looking for a good block. The .010 and .020 are hard to find.
