Darin ans the guys are great to work with. My 1st motor he me lasted about 5 years of very hard use on nitrous. I can't wait to run my new one with the F1A94 PROCHARGER. I broke the crankshaft on my old motor because I know how to party. They will always be my go to. Darin always helps me put together a strong motor because he knows that I'll test it to the limits and beyond!!!!

Great place to have your motor refreshed or completely overhauled. Did my 1962 MEL 430 and it runs strong. Daren and his crew were able to save the passenger side head that was horribly welded and make it all new again. Thanks guys.
