go ahead you'll love it.i have the 280 with 1.6 rockers in a 406 but have used it in a 350 bored .060 over as well.it will work better with an original torker manifold or an old holley strip domintor or team G " X " type manifold.any of the smaller X type manifolds should work well.they like to breath.i use a 2" 4 hole spacer on an original torker and the motor loves it.an rpm with the center cut would be ok or an air gap.i have the rpm with the center cut like the air gap but it seems to like the torker better.

Thanks for all the feedback thus far guys. It is too late to change the pistons because they've already been fit to the block and everything. So we're going to stick with the dished pistons.

I just got back from the shop and the machinist measured the combustion chamber CC's and they came out to 79.4cc's. That made the fact that we're using dished pistons worse. The block is all done and everythings ready for us to take home. The crank is the only thing left, it's getting turned right now then he's going to balance it with the harmonic balancer and the pulley that bolts on to the harmonic balancer.

In lite of this new info, the combustion chamber CC's and not being able to swap pistons, we've ordered up a 1500RPM Stall converter to use with the 700R4 transmission.

I just learned that Sterling makes two types of dished pistons thanks to you guys but I learned it after I got back so I didn't get to check which we have. I think it's the 5cc's but I don't know. If I go over there again I'll be sure to ask.

I was just cleaning the inside of the car last night and I found the owners manual from 1973 lol.

Ya know the original engines came with 8.5:1 CR. It's also got a 22 gallon tank!!!

It's crazy, coming from a 13gal it's going to be a monster to fill.

Hey thanks bob, that's what I thought. They're better than those low flow smog heads that could have been on there.

By the way, Welcome to Hotrodders.com

Just found out that the car's got a 2.73 rear end. With the 700R4 we put in it'll be turning 1600RPM's at 60MPH.

Just got back from the machine shop today and the machinist wasn't sure what CC dish we have. He said we'll just have to measure it when we got the engine put together.

Everything's done now, he's just balancing the crank and pulley and harmonic balancer for us, the engine should be all done by this Friday . Yay!

I have the comp cam magnum 270/470 in my 37 Chevy hotrod truck. Engine is 350 ci. standard bore with high compresion forged flat top pistons with 64cc chamber Vortec heads, ported and polished, Edelebrock polished medium rise intake and the best carburator I have ever run on anything. It is probably a collectors item, Carter AFB Competition Plus 700 cfm I think, automatic choke and the truck will crank if setting five days or ten minutes as quick as any car with electronic fuel injection. The compression ratio is guessing 10.5 to1 ratio. I run 93% ethanol free gasoline. The truck idles around 700 to 800 rpms with no stahl converter in a turbo 350 transmision with no creep or dieing at traffic lights.
The truck only weighs 1,790 lbs. with me in it and the engine probably makes 340+or-hp and I wish I could get it handleing as fast as it would run.
All this to say the cam has worked out good for me and makes good power from 1500 to 4,000 rpms.
