On my previous engine my top speed by GPS was 99.5mph on a slight incline.   Only mods were a Weber 32/36, original cat from the 80s but with no pipe after it... some vacuum deletes, and 165/80/13 rear tires xD

I've had it up to a true 100mph on flat ground a couple times. I have made the speedometer hit 100mph on back roads following regular traffic dozens of times before, too. The speedo reads 5-10mph high from 40-70 and 10-20 mph high above that, in my car.

I did blow up that engine though... trying to limp it home after some massive oil loss.

But I just finished swapping in a much lower mileage, older 4AC that has apparently been using full synthetic, and doing a lot more deletes (AC, heater bypass, etc) and should have had a Fidanza flywheel but they sent me one that fits the crank but is 2cm too large...

Anyway, after I get that all buttoned up I'll see what this one can do, it feels much more powerful O:

bogs downs sputters n shuts down ive switched carbys n spray carb clean n no change so i think its no leak. im thinking maybe my dizzy n probly just puttin a 3ac instead hopefully it help would a faulty dizzy mess with rpms ? cuz my car in neutral can rev high but in gear .. nada =/

I have broken 2 speedo cables on my 83 AE71 4AC... Had her well past the 80 in the dash... Looking into an after market speedo that will go into dash... (Good for those Cali Runs)
