What's that thing worth 75 grand?

Gosh ... back when they were new & the hot package to run ... they were $55,000 ... a race ... on a lease deal. Now, they don't run that engine anymore ... so a guy can probably get a nearly new/fresh one for $20-25k. Of course worn out junk is out there for a lot less.

But rebuilds are killer. Too often & too much! Hey ... that sounds familiar.

Ouch!

I'd say more cubes so you can make it less rowdy. A quality engine should go a season and then need maintenance, not rebuilt. I wouldn't want to give up much rpm for road racing. How tight are you spinning it?

It gets old real quick!!


Pete is here in Sun Valley -- and came down to the shop today. He was having all manor of valve train issues with his 347 (same cubic inch as mine) and finally put a 6300 chip in the MSD and hasn't had any problems since. Maybe it's all my doing IDK.

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.
