Hi,
Look at Johnson's Speed Warehouse on Ebay. They have lots of old stock of performance parts. Many forged 350 piston sets.

Hi,
Speedway makes an .024 steel shim for the 400. That's the only one I know of.

Hi, anyone know of a site that has helmet reviews or comparison? Or even a quick tutorial on what to look for when buying a helmet? New 2015 rated helmets are available now. I've heard all the "what's your head worth" comments before but I'm just an amateur, occasional user and want a valu...

Minimizing reversion between cylinders?


Rick

I used to run some demolition derbies and it's actually amazing how long some engines will run without coolant. I had an old early seventies Cadillac that we ran after the derbie without coolant or oil and we couldn't hardly get it to die. It would die and then start right back up again. We were hop...

Is that why the valve tips are ground down all the way to the keepers?

Hi,
Read this: http://www.carcraft.com/techarticles/13 ... akes_test/

The Holley 300-25 was ranked as second best in Peak horsepower and fourth in Average torque. It was mentioned as one of the best overall manifolds

Hi,
I don't know about cars, but on trucks the stationary regen only happens if you flip a switch. They do get very hot while driving and get really hot during a regen. I would look for a more conventional reason for the fire, ie. oil leak, fuel leak, electrical short, etc.

Hi,
Lots of food for thought. Here is an interesting test:

Hi,
I have always thought that a dual plane tunnel ram would make an awesome street manifold. A la tork link but a true divided plenum dual plane with some very long smooth runners.
Rick

Hi, I'm far from an expert but I think you are really missing the boat in not trying a Performer RPM dual plane. I have seen many published dyno tests showing that this manifold is very capable of making 550 HP or more if worked over. It may not make a lot more top end HP but it will definately add ...

Hi, Your customer is right, they do run a long time without water. We ran them in the derbies and then tried to blow up the engine afterwards with no water and they just wouldn't die. I always used synthetic oil. Lots of guys use Slick 50 or other additives. Pure water with Water Wetter or equivalen...

On those ebay heads... how do you get a pre-87 intake to cover the tall vortec ports (or do these have standard pre-87 port dimensions at entrance)? My understanding was that most dual plane intakes don't have enough meat above the port to seal the taller vortec ports. :?: I bought a set of those h...

Joe doesn't exaggerate. How about 813 HP out of only 400 cubic inches!!

Hi,
These seem to work in some applications.
