According to Ron Williams, SMTSE, Southeastern Regional Mgr. for Sunnen, the proceeds from the raffle all go to charity. One hundred percent of the money raised from the Rev It Up Raffle will be donated to two well-deserving charities, the Tony Stewart Foundation and the Special Olympics of Indiana.

Sunnen has been participating in charity performance engine builds for the better part of two decades and some very exciting performance motors have been raffled off, according to Williams. Last year’s motor, a – a 600 hp, 411 cid plant built for UMP Dirtcar Modified competition, built by Earnhardt Childress Racing, was won by Don Fultz, Fultz Racing, West Lafayette, IN, who,  conveniently, had a UMP Modified Chassis in need of a stout powerplant.

According to Sunnen’s Williams,  “The past few years we have had famous engine builders supply a basically de-tuned race engine for our Charity Raffle Engine. We are going back to our roots for the 2011 engine. This will be an engine that, if won, can be installed in the winner’s muscle car, street rod or truck.”

The “Rev It Up Raffle” will feature a Jasper Class II Performance engine, Chevy 350 cid, a great choice for performance-oriented cars and trucks, street rods and restored muscle cars. The Sunnen IMIS team will be adding other components such as the carb, intake manifold, water pump, distributor, harmonic balancer, etc., from a diverse group of well-known industry suppliers.

According to the results of our annual Machine Shop Market Profile, the Chevy 350 continues to be the most common engine rebuilt. It’s dominance has slipped somewhat over the years, but this year, the small-block Chevy was ranked as the number one engine rebuilt  by 37 percent of shops.

The version produced by Jasper will produce approximately 350 hp at 5,500 rpm and 380 lbs. ft. torque at 4,200 rpm.

“The Class II Performanc engine is for the serious performance minded person who wants power for a specific application,” explains Darren Ragsdale from Jasper. “It’s perfect for performance oriented cars and trucks, street rods and restored muscle cars, small/medium size engines requiring good low speed torque or for OEM replacement.”
