Sounds like a pretty good setup, especially the Blockzilla - small bore with a long stroke though, hmmm.....

I didn't know McGhee made clutches. If it is the same as the Shockwave (made by Jr Racecars in CO) then it should be a pretty good unit. The 33mm carb is the standard for the 8.90 class, won't need the 42mm till you go 7.90's.

The older car with the Raptor, Clements head, cylinder head, flywheel, etc... sounds like a good 12.90 combo. We are just wrapping up the 12.90 class with an engine that can run low 11's, but we slowed it down to 12.90's by doing a variety of things. Let me know if you need help slowing it down - if your driver is under 10, and quicker than 12.50, you are bounced for the day. [img]<<GRAEMLIN_URL>>/eek.gif[/img]

Post some pics of the cars, maybe we can decipher the older car. Sounds like it could be a Monaco. Where is Dominic? He is the site expert on all things Jr! [img]<<GRAEMLIN_URL>>/grin.gif[/img]
