Re: 1975 350 Modifications (pillowmeto)

ok James, I will respond back to you with the gyno results. Also, FYI I did replace the cam with a Comp cam 260H so the dyno run will be with this cam vs the original stock one. I am interested to see what I get with the cat gutted vs Dynomax headers and true 2.5 duals

I, too, have a 75 Vert....wanted more HP! Here's what I did and it dyno'd at 395hp...to rear wheels!

1. Speed-Pro 3/4 Race Cam
2. Speed-Pro Hyperutechtic Aluminum Pistons
3. Holley Pro-Jection 4 (Throttle Body Fuel Injection)w/High Rise Intake
4. Hooker Headers
5. Flo-Master True Duals
6. Changed out the stock Auto transmission with a 350Turbo Automatic (faster hole shot & better gas mileage)

Thanks Vetteguy. This is very encouraging. Could you provide more information about each of the components that you added, such as approximate costs, more specific part name or number info, as well as where you got the parts from?

btw - is your car painted the original silver, I believe color code 13?

Thanks,
James
