SR5 - 4A-C engine

Ivan,

You are forgetting taking the stock carberators off and putting some nice webers on them

Really, just take a look at the paradise racing site, there is alot more to be had for the 4AC than you think.

It just never will be fuel efficient

And yeah, I guess when you got the 4AC running with that gear you would have spend more then buying a good second hand 4AG. If you have the tools, room and knowladge to do the swap yourself and forget about the rear axle mods, brake mods, suspention mods, etc, then it probably wont make much difference.

But if you have to let someone do the swap for you, hell you'll spend a whole lot more $$$ then tuning a 4AC

Then again, I dont have any hands on experience with the 4AC, I'm just going on what little knowladge I do know about carbed engines. With carbed engines having some good carberators can make all the difference in power especially compared to stock where fuel efficiency was more on the minds of the manufacturer then power.

Jamie, owh I thought from his site that he was doing a turbo on a 4AC. Well I dont speak the language so....
