Yes they are, I was going to build up a 400 [still have that] for my 90 burb but decided to go with a later model 350 block with a factory roller cam and a forged 383 crank. more computor friendly with TBI. I have also for sale if anybody is interested a 4 bolt main 400 with KB .020 pistons. It has about 85k miles on it and needs a little fresh up.

c-tenkid · 10-20-2003, 11:15 PM

What valve springs are those?

I might be able to come up with the money in a few days.I am really interested.These would work good on my 408 I am building.

**kwmech** · 10-20-2003, 11:55 PM

If I remember right those are crane springs for a matching 268 cam. They have been tested for poundage [is that a word?]

To sum it up in a nut shell-- they were an early 350 hi-performance cylinder head commonly found on the camaro and corvette.
