Peanut Port Drag Test
For several years I've been building 9.2 compression 467s with 236 peanut port heads, these engines use a 228/238/114 hyd flat tappet cam with a performer RPM intake typical HP was about 517-518 corrected HP, with about 560 TQ. Finally it looks like I will get to test one in my 68 Chevelle, 3720 pounds at a 2130 foot track. My goal is a high 6 sec pass in the 1/8 mile. Some pictures of the build.

Re: Peanut Port Drag Test
That's cool. I always considered "Peanut Port" heads as No Good. How much RPM were obtained with those figures.
Those heads only came on "truck" motors, right? Could not build a traditional stocker motor because they never came in a passenger car, correct? Will Lamprect i/SA 65 Impala in progress. 396/935 "Oval Port" |

Re: Peanut Port Drag Test
73-75 are allowed the 236 peanut, 90 454ss truck uses the 360 peanut, 91-92 uses the 148, even smaller peanut port. Seems to be plenty of SS/GT 454's using the 236.

Re: Peanut Port Drag Test
I remember hearing that Lingenfelter ran a killer peanut port combination in SS back in the day.
