I'm looking at buying Mac's Comp flat tappet cam & the only thing thats bothering me about it is that is has 110 LSA w/ 218 dur. .454/.454.... Is 110 LSA alright or will vacuum be a problem thus giving the computer fits....It would be going in a 350 TBI along with Holley 670 TBI & edelbrock intake & eventually Trick Flow heads

Thanks,

it will have a little less vacuum at idle with the narrow lobe angle, but with a 350 it will swtill have a ton of vacuum to run the computer.

110 here and good vacuum.

 

That seems like too much duration for the LSA. I think it might send the computer into fits, especially when you change the heads. I would look into gettin a chip burned.

 

Turbo City sells a MAP sensor corrector that might help you out.

 

Alright thanks a lot guys....I want to start burning my own chips so I think I'll go ahead & get the cam & then look into theat MAP sensor corrector for now

Thanks again,
