SBC Block Question

I am presently the owner of a cruddy 2 bolt 350 block (the same one seen on the webpage). I talked to the local race engine machinist and he said the 2 bolt block is just fine to about 600hp if ARP main studs are used. I have no reason not to trust him on this one but do question his advice nonetheless. Will I be fine with the studs and 2 bolts or shoudl I break down and have splayed caps put in (~$400.00)???????

I was told basically the same thing. Basically the 4 bolt was to prevent the crank from flexing under really heavy torque, like when a truck is pulling a very heavy load, or when an engine is being sprayed really heavy off the line. I think you should be fine from what people have been telling me about the 2 vs 4 bolt mains

I was told the same thing, and would have went with a 2 bolt block, but the builder had a 4 bolt prepped and didn't charge me extra for it... It was a Bowtie Unit ordered by someone else and never picked up...

Hey SpencZ - Can't believe what you have done to that car - ya got guts man! Anyway, just thought I would pass on a crazy idea. Speedway (402) 474-4411 is having a sale on Cadillac Northstar V8's. DOHC 32 valve 4.6 litre, 300HP and 400 lb/ft of torque for $2,500 brand new in a crate.

hey save your $$$ northstars suck

for that kind of $$ you can have

a 450 hp 383 if you build it right....

and we build 400-500 hp 350's on 2-bolt

all the time for circle track and they work fine.....

we roast valves way before the bottom end gives up...

we have never seen a 2-bolt main give up

even at 8000 rpm......

but we have seen rods/pistons crater

just a note on this.........

OK guys... Lets all take a deep breath....This isn't Zcar.com! Lets all act like adults.

 

There is no such thing as a bad idea, even in failure... Learning is the key.
