Mya baby Posted August 3, 2020 Author Report Posted August 3, 2020 Mcdermott racing. Right now the set up i use it for is ice racing and it works well just locking for a smooth power curve. Going to power value Quote
grantevans713 Posted August 6, 2020 Report Posted August 6, 2020 I'd be interested in the cylinders, pistons and intake, I have a coolhead, pipes and reeds already. Quote
Mya baby Posted August 6, 2020 Author Report Posted August 6, 2020 Give me a call we can work something out i think. 262-442-5271. Thanks Quote
HOODWORKZ Posted October 21, 2020 Report Posted October 21, 2020 Hey I'm curious when did you have Harry from McDermott port your cylinders? I wasn't sure if he was still doing work and like him to work on my 421 cheetah pv. Thanks Quote
