ESR Heads and domes

[69-ss-396]

Are the heads and domes (Pump-Race) the same for the 310-350 Cyl?

The Shells and Domes are the same for all ESR 310-350 cylinders as well as interchangeable with ProX cylinder kits as well. The Dome CC's are different for the 310, 330 and 350 cylinder kits in ESR & ProX kits. The difference within the same displacement (330 Race Fuel verses 330 Pump Fuel) sometimes is minor, and accounts for the reason why the difference in compression between a race fuel and a Pump Fuel Dome can be as little as 10 lbs...

Thanks!! I'm running a pump gas in my 350 pv and had a extra race from my 310 and just wanted to make sure it would work before I tore it apart.. I run race gas in both machines with pump gas dome, Will I be able to see-feel a difference with the race gas dome Or should I just let it be?

It will make a difference, try selling your extra dome and get a race gas dome specific to your 350.

As RK88R suggested; get a Dome specific to the 350CC's...DO NOT use the 310 Dome in a 350CC cylinder; way to small.

You can also have your 310CC specific Dome re-cut by a local builder or machine shop to work in your 350CC cylinder. If you have someone local, I can give you the CC's needed to convert the 310CC Dome into a 350CC Dome. If not; call us and we can re-cut to 350CC Dome for you.

That is correct, none. There is a small cycle shop here in town but they don't do nothing like this...

Do you know where Neil is located??????

[69-ss-396]

Yeah, by no means local. I have delt with the guys at BDT over the phone, through ebay or there site for a few years now and only found out about c leigh when I joined this site.. I'm sure he does great work and will more than likely use them for something down the road.
