Umm...LOL. You do know how to read right? That thing could pull a 3.08 and still be fine.
I only make 370 lb/ft and 200 HP at 2800 with a 3.08 and it does just fine.

OP, Really nice job all around. Engine bay, interior, exterior, paint, it all looks great!

 

Rear gear is mated to a T56 magnum 6 speed. Shift points are excellent for launch, country roads and highway.

Beautiful car, love those big blocks!

 

I bet ya are leaving 20 hp on the table with that 750 And I say this because a dyno test was done on a sbc 427 nothing altered at all except carb,started with a 750 and went to 850 and the hp gain was sorta shocking all of 20hp and better torque .

And it was on the climb but as you can see the test stopped at 6200


Of course I can not say that will work with your set up but 750 seams a bit small for that set up your running.

 

............and the front centre grille that replaces the license plate frame?

 

Nice car myc3.

 

The center grill was the last piece to be found. Once all three metal grills were found all of them were sand blasted and powder coated silver. All pieces were found over time on ebay and vette forums. I really wanted the last C3 bumper with metal and without bumperettes on either end

 

Thanks for the positive comment - appreciated

 

Thanks for the info. Nice to know that a bolt on part could make that much difference. My engine builder chose the carb and I was happy with the dyno results. I did not have multiple carbs to try on dyno day.

BTW - I am in upstate NY near Saratoga. I went right by you on my way home from South Dakota when I was driving the car home about 2 weeks ago.

Having trouble finding anyone to tune this carb in my area. Does not like to idle below 2000. Any suggestions?

 

Very nice. Love that clean blended look.

 

Thanks - you are right. There is torque on demand. Having fun learning how to drive this thing.

 

Thanks - the goal was to get rid of the seams, bumperettes and add the best C3 parts to one car . It still looks stock and the lines sure are nice.

Up until a few weeks ago this was all theoretical. Now it is in the garage.

 

Where in SD are you?

 

I am in Upstate NY, just outside Saratoga. I was in South Dakota 2 weeks ago to pick up my car. That is where the body work and final assembly was done. I drove it 1600 miles to get it home.

 

Nice, where did you get the hood from? One would never know what you have until its too late

 

It was from Ecklers

Ok I had it backwards. Where did you get it done? Did they do the paint as well?

 

Custom Image Corvettes in Watertown SD did the body work, paint and final assembly of the components I provided
