Re: Quadrajet lean spot.

You can't escape the fact that since that Carb is now on a 350 it's going to want to near 10% richer across the board just for starters!

Re: Dodge StreetVan w/360ci Alu.heads - ProFlo4 - Camchoice

For the highest Torque output from that 360 cid motor you want to run a good amount of valve lift ( into the low .500s ) to both take advantage of the motors lifter size and get deep into being near the max flow level that the Intake side of those heads have to offer. The weight of that Van and its ...

Re: Camshaft RPM range?

You can't truly state a given Cams power range until you know what the minimum port diameter is in the full Intake tract.
There are a few on line formulas you can use to do such and they seem to get you to 10% accuracy or less.

Re: Modern Engines & Static CR vs. Boost Levels?

The fundamental rules and pluses In regards to power of having a motor with high static compressions don't change even with 6 camshafts and a 10 71 blower feeding 4 turbo's! The higher your boost pressure the more heat gets made and more you need to cool it before it enters the Intake tract to make ...

Re: another balance question

My main concern would also be for the unneeded weight placing a greater load on the Rods.

Re: another balance question

A lot of engineers state that even 25 grams of unbalance is not a issue, but this it at 7000 or so rpm, at 9400 I would want far better tolerance then 17!

Re: Straightened crankshaft revisited

The undisputable fact is this, if the Crank ever gets subjected to the same stress loads that caused it to bend the first time then it will bend again . If it where me and I did not want to go thru that again and if the Crank was not a 150 lb truck Crank then I would send it out to be cryogenicly tr...

Re: Where do I put the new rods?

If you only have a 6 counter weight Crank then put the heavier Rod and piston assy near the front and rear of the motor, not near the center where your missing 2 counter weights ! Also if the Rods your reusing have have more then 4 torque up session on the bolts them then your playing with Fire agai...

Re: BBC intake mods

I say this because back in the late 90s I had a .030" over 455 cid street strip motor of mine one a dyno and the Q jet was giving us issues so we got that worked out and with a 1 inch spacer ended up making 406 hp at only 4400 rpm, this was with a Performer Intake. Air consumption was only 645 cfm s...
