[69FIREBIRD76MM]

My buddy built a ford Mustang fox 306 cid. block, Pretty basic. That thing will run 7.20 at the 1/8. Drove it every where. There is other brands with smaller engines running faster than bbc.

I wasn't expecting huge results due to the hot weather compared to the last outing..I will check the DA of both days to see what it was...Ran five times..1st pass 11.23/121.28 1.6469 60ft,2nd pass 11.21/121.52/1.6457 60ft,3rd pass 11.2179/121.97/1.6810 60ft,4th pass 11.2052/122.23/1.6782 60ft,5th pass smoked the tires track got dirty from some trucks 11.566/121.92/1.8879 60ft

Beat the old best by quite a margin in warmer weather..the tailpipes were a restriction.

Are you running just the dumps after the muffler?

Do you think the gain was from less restriction or from the shorter pipe length of the system tuning to a higher rpm and helping the top end charge? Those Ultraflows look like a straight pipe to the motor so maybe tailpipe length affects the torque curve somewhat.

"As far as power is concerned, tail pipe length after the mufflers has no measurable effect on the power if a large change in cross section is present up stream (toward the motor) of the tail pipe. An open-type muffler, or a resonator box, provides this cross-sectional change. The tail pipe length exiting most glass pack installations is also of little consequence if a resonator box is used, but is of significant influence if not."

It won't be long and he will be making 10-second passes

I don't think he's tried it yet.

Ok.

I have Torque Tech Daul 3.00 on my 1970-1/2 Trans Am.
Tailpipes included.
3-1/2 to 3.00 Long length collector Merge Reducers.
About 18.00" overall lengths.

The 1085 Bo Laws carb of mine I was told to run True 4.00" ID On the 410 sbc of mine with that carb.
Open 4.00" Header collectors preffered.

The Math Science of Pontiac V8 is unique.

Test with what he has.
See what happens.

NOT

Exactly why the fastest Pontiac guys have their stuff done by builders who do NOT specialize in Pontiac. FACT

[wheneaglesfly]

How much HP ARE WE TALKING ABOUT ?
HOW MUCH MONEY REQUIRED ?
2 MILLION DOLLARS ?
4,000-10,000 HP ?

ITS STREET PERFORMANCE. & STREET RACE SECTION HERE.
PONTIAC BUILDERS.

HOME DONE BUILT.
LIMITED BUDGETS.

YOU CAN TRUST CHEVY.
I WON'T.

ONLY FORD GUYS TOO.

I gotta say Pontiac is unique in that it doesn't take "race parts" to go "fast". Show me a Ferd or Chebby guy going low 11's with 3 speed Autos, 3000 stall converters, 240ish duration and .600ish lift HR cams, and friggin 3.08 gears in 3800-4000 lbs street machines!

And doing this with pump gas while not overheating in traffic, hard to beat a well built Pontiac! Plus we actually work harder on our stuff to squeeze more performance and reliability than your average Chebby guy.
