i just got a 454 throttle body from ebay. the guys says that it is from an '89 truck. he also said that he did the afpr mod. should i be worried that he somehow messed up the afpr mod? just wondering what i may have gotten myself into.

any tips on recinditioning the throttle body at all? anything i should look out for?

thanks guys..i apprectiate it.

no worries, your injector pod is the same as the one thats on the 454 unit, youll need to run your injectors anyway

 

z28 boy, I thought you already had the holley 670 unit? What are you doing with the 454 unit?

so i am going to use my injectors, and that will be enough fuel? what is the stock injector's flow rate?

i am assuming that the increased fuel pressure that i will be running will compensate for the smaller (stock) injectors, am i right?

Jon...the reason that i am trying out a 454 throttle body is because everyone says that the holley unit is garbage, so i thought i would try it out. and i still can't get my TPS set right on my holley, so hopefully the 454 will be better in that respect. i think that the TPS issue has caused a lot of my problems.

thanks guys.
