If I can spin a big block 6800 countless times, that little small block should do it all day.

I think I have a 7000 chip in the MSD -- but it might be less -- and I've NEVER hit the limiter. The Lotus I hit all the time - because I can't hear it with my new helmet (has communications built in and the ears are quiet as hell).

I think that motor - with it's titanium valve train - and built by a top notch builder -- should run for 4 years of track days doing nothing but adjusting the solid lifters.... So either I'm doing something to it - damned if I know what - or there's some geometry issue that isn't being caught. Thus a fresh set of eyeballs will be in order. Unless I broke it real good.... and in that case a new motor will fit the bill --- or be on my bill! LOL

First thing that comes to mind is the titanium valves are causing you problems. Seems overkill for a small block with a 7k chip. If it doesn't have shaft mounted rockers, that's a must. I'd say the titanium valves warrant setting the valves HOT. Who knows what happens at road racing temps. I'm just throwing things out there. Me, I'd put a less radical combo in it or let Ron go through the entire engine.

This would make a nice addition.

Jack Mauer says the motor is a 356 cubic inch

I seem to remember the numbers working out to be 355

Well, it's apparent why Charlie struck you such a sweet deal.

Previously I've heard 355, then 347.

It's a small revvie Ford with a very good power curve...........when it's running.
