Upgrading my 340

I'd bet the headers are hooker 1 5/8" style.

320RWHP should be a bunch better than 100 mph.
They're not hookers, I was really low on funds at the time and I thought any header is better than stock exhaust manifolds. These cost me around $200 new and we're a pain to install. 11/2" pipes. They've got to go soon and be replaced with 1 3/4 tti's
I've gotta run to help restore the bodywork/laint. Thanks to all who are trying to help me produce more without opening up the engine back up. I'll be back soon!
