Ok...winter project time is approaching...considering doing a FIREBALL upgrade, however $$$ maybe an issue. So I thought of just going the CLUBMAN route to get a bump in performance and keep my cost down a bit. Tom, I'm familiar with the upgrades involved in the FIREBALL conversion...could you educate me on the CLUBMAN level please.
Thanks Tom...good info...
what about using the stock crank shaft and main bearings, and upgrading the ignition to a Boyer ignition.
The Clubman head mod is basically a porting job with high-quality big valves and our custom valve seat angles, and some valve stem seals for oil control. It is essentially the same port and seat angles as the Fireball, and it can be upgraded to a Fireball head later on, since the porting is already done to it. The valves are not the same as the Fireball, because the Fireball uses different valve gear that requires a modern valve stem cut for modern valve locks, so we use the Kibblewhite big valves that have the old Enfield style retainer cuts for those original valve locks, and use your OEM valve springs and parts. This keeps cost down.The intended arrangement of the Clubman set-up was for a budget system that gave very good results for the money.It is intended to be used with re-phased stock cams which obviously will have the stock lift height, so the head needs no special springs to handle high lift or deal with aggressive cam profiles, since the re-phased cams are stock cams with only a valve timing adjustment. And you just re-phase your own stock cams, so there are no cams to buy, and that keeps cost downI have been rather shocked, actually, that more people have not taken this Clubman route. It's amazingly good for the cost of it.
Tooseevee,I think that the best thing I could recommend to fit your stated requirements is to let us do a performance valve job on it.This is a fairly low cost procedure that will not change the basic character of the engine, but it will flow more air at all rpms, and so you'll get more torque and hpsnip snip snip snipWe might be able to do some roller rockers on that head, if it turns out to be similar to the "Big Head" on the iron barrel bikes. But that's a lot more expensive.How's that sound?
Sound like a plan.Looking forward to it.Thanks,Tom
Sorry Tom, I feel like an idiot. For being a history buff, I've just proven the old adage "Do your research FIRST before you stick your foot in your mouth" by sticking my own foot in mine. I thought YOU were Joe Mondello & I've just gone & found out that he died in 2011. So sorry. He must have been a great old guy & aren't you lucky to have known him?
