Hey guys! After having installed a new intake (RPM AirGap) this winter my 340 is really difficult to start when cold. It’s an almost stock engine but slightly cammed. It has a Holley 750 DP without choke on it now and I’ve never had any issues doing cold starts before I changed the intake. Now I...

Hey guys, wanted to get your input on something. Just about to put my 340 back together again and when test fitting the new air gap intake I noticed this, the intake doesn’t cover the upper “horseshoe” part of the crossover. I had expected to have this sealed off by the gasket but I didn’t...

Sorry if this issue has been addressed somewhere in the past, I tried to search for it but the main issue people seem to have with ball joints is the shaft and/or socket size! I'm in the process of doing a disc brake conversion on my -72 Demon. I bought the disc brake kit used (I believe it...

So I’ve got a recently built 340 with a Comp cam in it with 274/286 of duration and 488/391 lift. It only makes around 8-10hg of vac at idle, and I’m pretty sure there are no leaks and compression is good. I’ve got it set at around 13-15 initial and 28 total right now, which is as far as my...
