Doing a 340 for my son's Duster. I have two chain sets. One is a Howard's Cams unit. Sprockets made in USA with a Rolon solid roller chain. Second one is a JP performance, made in Australia. Iwis chain with split rollers. Engine will have a .530 lift hydraulic cam calling for 300lbs open...

I've been searching the web for replacement SS valves. 2.02/1.60. Length seems to be longer on them all, with Manley being the closest to a stock length valve. I've considered going to an 11/32 stem chevy valve because I need guides, but the length I've found on the .100 longer chevy valve is...

Ok, so I have a .030 over 340 going together. I'm used to using file fit rings. My question is for those who have used the KB Hyper pistons. How did your ring gap come in? Being that these pistons require a larger gap, did you have to file a standard .030 non file ring? According to KB's chart I...

I need a set of file fit rings for my .030 over 340 with stock 5/64 ring land. The only ones I keep finding are for 1/16 rings. I used to buy these years ago but cant seem to find them now. Checked Summit, even called them. Checked Speed Pro site as well as Mancini. Help! LOL

I'm banging my head trying to figure this out. I want a piston with the factory compression height of 1.840 which is 10.5 to 1 factory spec. I've found two after staring at the internet for two days. One is the old reliable Speed pro/TRW slug and the other is the KB 243. I've ran the old TRW...

Doing a set of 2.02 J heads, and some stock valves are questionable. I was considering a stainless set, but started wondering if the stainless valve would be harder on the stock seat in todays unleaded world. Car is a weekend driver with 500 lift Hyd cam, so more spring pressure than stock.

I'm using a stock 10.5 to 1 piston and wondering how the valve pockets compare to a replacement TRW piston in depth. I'm hoping to run a 540 lift cam and wondering if the stock valve pockets are going to be a problem. I know duration plays a part. Just wondering what people have gotten away with...

Would anyone know the weight of a factory 10.5 to 1 piston?

The time has come to detune my 372 for a more comfortable driving experience. Its in a Dart Conv. and I'm ready to change it up. I built this motor about 15 years ago and it has been trouble free, but the local track closed and street racings not what it was. I was wondering if there's any down...

Gathering parts as I go and would like to know which air cleaner is right for 1971 340 Duster. Pic if possible, thanks.
