so im about to do the cam and stall swap in the spring agian but ive never done one this big and im curious what it gonna do to my gas milage. not that it matters cause im going to do it anyways and im not concerened about it im just curious. the cam specs are: 236/238 .601/.605 113 LSA and im going to use a 3600 stall form yank most likely. im still debating on that or a tripple disk from circle d. another question i had is am i going to change injectors...im pretty sure i will.

 

it's gonna go down. you're probably gonna lose 1-3 mpg.

 

with the mods in my sig i get 9-10city and 20-22 highway... The LOOOOOOSSSSSSEEEE converter soaks up the MPG during city driving...

 

gas mileage will go down... yes bigger injectors will be needed..

 

What injectors do you have now? That cam is definitely going to need some high flow injectors

 

If you plan on running a cam that big, a verter that much, you really shouldn't worry about your mpg's They will be down a bunch.. I would say 8 mpg city

 

im not really to worried about it. just was curious. i have stock injectors nmow but all i have in the truck im putting this in is a stock lq4 with bolt ons (cold air, headers, maf etc.) im looking at a cam just slightly smaller but it wont be very much of a difference. this cam might be just barely too choppy for me.

 

Well word to the wise.. You are wasting your money if you put a huge cam in it, with heads that can't flow what the cam can...

 

i know. i just cant afford the heads that i want right now. im throwing around alot of cash right now as it is. just bought a $2000 tranny and will spend 700 on cam springs and pushrodds and the converter will be around 700-1000. im only 19 years old so i dont have to much money at this point of the year. i planned on buying heads around next fall. i wish i could afford them now its just not in the budget. girlfriends are expensive man. mine dont understand all this wanting to go faster stuff lol.

 

man i want a cam so bad in my ss. but my mpg is getting better and better later with the mods ive done and lowering it.

my blue truck had a huge converter and cam and it got 15 mpg.
