what kind of crank and rods are popular with these cars? i have heard everybody just trys to go as light as possible and that makes the motors cost alot. i was just woundering what you guys had in yours. if anybody on here runs one.

I see alot of Eagle lightweight stuff----to each their own, if I was to build a new one mine would have a Callies crank and Carrillo rods or something very similar. My current IMCA engine (steel head option) has a Callies crank & Eagle H-beam rods....the rods will replaced here before to long.

i have been looking at a scat lw, or a bryant or a callies. probally anywhere from 55-40 pound range just depends on money.
and carrilo rods, protru pistons, brodix heads and intake, shaft rocker assembly, probally baout a 4 stage dry sump, and a decent carb.
would this be able to keep up? i thought i may wiegh more than alot but would last long and turn some rrrrr if i need them.

We bought a Scat 44lb 4340 for our SUPR spec motor. It is definitely a nice looking piece. Haven't ran it yet tho.

No offense guys but I'd be real leery of the chinese stuff (Scat, Cat etc...) and stick with American forged/American made. You can pick up the Callies Dragonslayer crank for $700 and it should last for YEARS.
Steve/Hendren Racing Engines frequents this board often, he'd be a good person to check with AND I know he has an opinion on cheap cranks.

I'd say to build from scratch an IMCA LM engine is gonna run at the very least $10k but to run up front it'll likely be closer to the $15k-$18k range.
