Hitting the dyno next week

**69blownprostreet** · #1 Jul 8th, 11, 03:52 AM

Went to the machine shop yesterday, the engine is all back together and were going to dyno it next week.

Going to video it and will see what the numbers are. I have another thread in the body shop fourm about the car. Winter project turns into summer project. Can't wait to start getting it back together.

What all did you do to the motor. Did you use the same pistons or change to blower pistons. I am going to rebuild my motor next year and have stock pistons in my 502. I will be boring it and changing to blower pistons.

Everything in the block was changed, full rotating assembly and roller blower cam. The machine shop that built the motor builds alot of blower motors and they use to race one. Who ever built the motor to begin with didn't build it right, didn't have a blower cam and all the internals I was told by the PO were forged and they were not so lets do this right, the only way I know how to do it. Like everything else with the car the PO made it look good but there was alot wrong with the car when I got it. I will have all the specs on the motor after we dyno it. Right now it's set up 1 to 1 but I have another blower pully so when we dyno it were going to run it 3 different ways, underdriven, overdrived with race gas and 1 to 1. It will be set up 1 to 1 to be street driven.

What size motor is it. My 502 is 1 to 1 and makes 8psi boost. I dont know the HP.

**69blownprostreet** · #11 Jul 9th, 11, 09:12 AM

It's a 454 bored 30 over.

1:1 in a 460 should make some great boost pressure depending on the the heads and carbs. My 540 with CNC ported Merlins and a pair of King Demons driven at 1:1 only made 6 psi. A 454 based shortblock should make alot more boost and be a real screamer.

Very nice looking engine. It would be fun to try to guess the HP. We would need a few more details for that though.

Looks like you have a PCV hooked up, Is that what I see? I use to run one and never had a problem, but after hearing so many horror stories about it causing detonation I got rid of it.

The heads are GM rectangular port open chamber Iron and the carbs are 750 blower carbs. The blower is a 671 teflon striped Littlefield. I will have the rest of the specs on the motor this week.
