Customer car featured in Popular Hot Rodding.

Congratulations go to Richie the tool guy who got his 1969 Chevelle into a two page article in the April 2010 Popular Hot Rodding! Rich, a customer of JM Performance, had Jim build him a 496 c.i. BBC with 590 HP and 603 torque. He then brought it to the track and did a best 1/4 mile e.t. of 11.34 at 120 mph.

Read the whole story and when your done check out the dyno test. Many other JM Performance motors can be seen being dyno'ed in the Products section. Dyno services provided by Sealine Dyno.
