Yeah this **** are slow stock... right now with the set up i got now.. hard launch spinning those 20's stock like nothing.. we both spin from the dig.. but i grabbed it launched hard ...
i remeber my numbers to when i took it to the track...
first time at irwindale 1/8 mile
intake superchiped flowmasters 3:73 ....11.1
second time
intake flowmasters jba headers 3:73 tuned ..10.3-5
third time
intake jba headers flowmasters 3:73 stall... 9.9 (untune for the stall)
so hopefully i can lower the numbers better with the new set up i got now and hopefully i can get it retune this month...

Yeah they are, tell me about it I had one in the past but a 350. TBI engines have like no power. Now, you can convert the TBI 350's and 454's to a Carb setup and remove the shitty stock cam and replace it with a much better one + upgrade heads and you will have a mild engine. You would need a fuel regulator and a distributor also. Hell just swapping the carb alone on the TBI engines would probably gain about 40-50HP lol.
