Re: SpeedMaster_ProCompElectronics_320CC_BBC_Heads

So I have to ask- if paying someone to do the work of making these heads 'right', how far away are you from just purchasing a decent set of heads outright?

Re: 2017 Expedition 3.5 EB cam phasers

There is eliminator kits- if you plan on keeping the truck.
The phazers have been an issue as long as I can remember- what kills them? Why hasn't ford fixed the issue- or is it a gold mine?

Re: Melling SharkTooth Oil Pumps and High Pressures: Is this a problem?

Talking with one of the Melling engineers at the PRI show, the "shark tooth" oil pump gears were designed to alleviate the higher amplitude pulsations that a normal SBC oil pump inherently produces. He said, producing those those gears did exactly what it was intended to do but, never mentioned pre...

Re: Melling SharkTooth Oil Pumps and High Pressures: Is this a problem?

I have the shark tooth pump in my 355, it's the one they claim as standard volume. It did have high oil pressure the first time I started it. It was over 90lbs when you would rev it. The pump came with 2 springs. I swapped out the spring for the lower pressure one and it helped. The spring that I p...

Re: Gm Fast Burn vs Ebay 200 Dart Pro 1 Copy

The exhaust port is raised but the bolt holes in the stock location. Takes some grinding and slotting etc to get a decent fit there. In the right hands the fastburn can be pretty damn good. If you can buy them for the price of Chinese heads i would buy them regardless if you use them on this projec...

I've heard tell that some of the best running engines had piston witness marks on the head.

Re: Evans Coolant

Zero pressure means- rad cap is disabled and system has little to no pressure. Comparing a DD capable coolant (Evans) to a mix of water and water wetter- is not a valid comparison, I guess it does show something, but I wouldn't use the later mix anytime. Because Evans is some 20% less efficient than...

Re: ATK Aluminum SBC Cylinder Heads

When I was looking at some heads- I looked closely at the GM Fastburns- they had a funky exhaust bolt location that killed it for me.
