Unfortunately I had a catastrophic event last Friday and windowed a block. Now it is time to pull it apart and fond out what happened. Its a 425 nailhead 1966. So if anybody knows were there is an affordable core block in case this one can't be fixed let me know.
Also I will be closed from sept.4 to sept. 14.

Ran this 523 Ford last night. Made great torque a little lite on the horsepower. But the cam is lite on duration and it has a small intake on it. Should be a ripper on the street. He will probably will have to buy stock in tires.

Last friday was a rough day on the dyno with the heat, but we did it mild 429 ford Edel head, small hyd rolle, andr mild compression street engine. should be fun.

Video got compromised but this is a 300 ford with a small cam, split header and duel Webers'. Not a powerhouse but about 70 more horsepower and torque. Also moved the peak torque down to a more usable level for cruising and some towing.

Well I finally got back to the 400. Was going to do a dyno comparison of if you were to buy a set of swap meet aluminum heads and drop them on your engine. When I went to tear off the heads I decided to look at the lifters. Found two that didn't look like they were wearing right. So measured the cam and 2 lobes were .010 small. So I pitched the cam. I put in a roller with similar lift, duration and lobe separation but same centerline. Found a set cheap speedway aluminum heads, narrowed the guide boss, cleaned up the ports and bowls and then gasket matched them. Used 2.05 1.6 valves. The old heads had 2.02 1.6 valves and no port work. Here was the results of a afternoon of tuning. First pull was 406 hp, The old engine was 360 after tuning, and ended with 433 hp and 483 lb ft. This will be fun.

Hello everyone, due to outrageous utility bills combined with rent I will no longer be open during the winter. It is making it pointless for me to open and heat my space with not having a lot of customers during the winter. This will be starting this coming winter. Thanks Bryan
