I have a 69 Camaro with a 350 Goodwrench engine. The engine has been modified with the following pieces, Chevy #186 casting heads with 1.94/1.5 valves, 280 Magnum Comp cam, MSD dist. & 6AL ign box, Edelbrock RPM Airgap intake w/750 Edelbrock carb, 1  5/8 dia. headers w/3 inch exhaust and race style mufflers.

The trans is a Turbo 350 w/stock converter and no shift kit. The rear end has 3.90 gears and positraction turning a set of 26 x 10.5 x 15 ET Streets. This is a stock body all steel car weighing approx. 3400 lbs with driver. It runs the 1/8 mile in 8.75 sec. at 81 mph w/2.09 60 ft times.

I have a 10 in. converter (nib) rated at 3200 to 3600 rpm, that I was thinking of installing. I don't know if this is too much or should I use a lower rated maybe 2400 to 2800 rpm.

Any suggestions would be extremly helpful.

Also if CHP is listening I would like to suggest that when you post dragstrip times on your projects that you include the 1/8 mile and 60 ft times because a lot of the tracks are only running 1/8 mile due to land contraints.

IMO, based on your combo I'd opt for the lower stall converter (2,400 - 2,800).  Particularly if you drive the Camaro on the street. 

If you do any street driving, the higher stall converter will not work optimally with 3.90 cogs.  With 26" tires, at 60mph you'll be taching ~3,000rpm.  This being below the stall (3,200 - 3,600) will lead to the possibility of additional heat being generated because the converter will be slipping (not a good equation over extended periods of time).

If you're set on the higher stall converter - and do drive on the street - then consider deeper cogs.  Point being is you want the converter locked at cruising rpm.  This combination will really improve those 60' times also.

* On a separate note, consider some aftermarket 2.02" heads with some good flow numbers.  Unless your current heads have been heavily massaged, the aftermarket heads will offer a measurable difference.

Good luck.

Charlie this it Zrated again, I have a line on a set of 2.02 heads I am told these will make a hell of a differance over the stock heads I have, any idea on HP and torque ...........Thanks ZZZZZZ  

Go with the set up Charlie gave you. As for HP after the head swap around 375-400 with good compression.--Phil

To get 1/8 Mile ET from 1/4 mile ET, divide 1/4 Mile ET by 1.57. To get 1/8 Mile ET from 1/4 mile MPH, divide 1/4 Mile MPH by 1.238.
