Re: Intake manifold porting

The biggest thing is the runner at the plenum is trapezoidal in shape and goes to rectangular at the flange,makes it difficult to measure correctly. I have had intakes bolted to cylinder heads on the bench and pitot probed,its something to be mindful that you are looking for minimal flow loss but j...

Test was done @ Madcap in Denver, the baro IS correct. Observed or in the room HP was 524 HP before the correction. Vapor pressure looks high to me though for Denver.

Re: Modifying an LS 5.3 Head for Towing

So recently I was looking at how to get some more low end torque out of my 5.3 for towing. I looked at cams and most either have a lope at idle or are so expensive it's not worth the swap. So I decided to look at the LS head closer and was surprised by what I was seeing. A 5.3 head is almost 205cc ...

Re: oil slime

my 555 BBC always seems to create slimy, milky oil in the valve covers and the oil itself changes color to milky very quickly after an oil change. I've tried royal purple, AMS oil and cheap napa synthetic. Same results. My motor seems to create alot of moisture. The breather bottle gets water in it...

I’m putting a 650DP I’ve had on a 400HP engine onto a 500HP engine.
Do I increase the jets a few sizes?

Re: Nitrous Softening

Looking for ideas on how best to avoid wheelspin with a small nitrous shot.(100 hp or less on a 420 hp NA engine.) The car is pretty much has all the traction I can get it, and does well NA, so, unless the N2O comes on gently, it will spin. I would like to avoid using a laptop if I can. That is wha...

Getting a block drilled for the SB2.2 lifter pattern and would really like to know what diameter lifter is best to go with, with the .903" being as big as I would ever go. And all that being said, what bra...
