Last post wouldn’t let me post a video so here is the 403 cid on the dyno. Special thanks to performance for the dyno session.

A nice 403 cid LS we just finished up featuring an eagle crank and rods, SRP pistons, heads were sent out and CNC ported the intake and exhaust runners and we finished all other machine work on them finishing them off with pac springs. Making just over 600 hp to go in a street rod S-10. Better yet this LS has a carb and front drive distributor so the owner can do his own tuning!

Day late and a dollar short like always on posting to the page. But huge congratulations to Jim Thurston for getting the job done a week and a half ago. Thanks for making that HHP power look good.

3 years ago today I went on my own running Holthof High Performance as my full time job and I wouldn’t change a thing. Just wanted to shout out to all my amazing customers/friends for trusting in HHP and making my dream a reality. I couldn’t be where I am without you!!
