Depends on what you consider cost friendly. Some guys on heres version of cost friendly is parts under 5 grand. lol

 

lol like 50 here 100 there? will new plugs get me alittle more get up and go??? i got new wires there factory tho

 

im pretty sure u got all of the lil mods out of the way besides a underdrive pulley...
but honestly teh next mod should be a 278mm Circle D stall..

 

You can always put 4 or 5 gallons of 110 race fuel in it! Synthetic fluids?

 

i was runnin royal purple, and switched back, didn't notice any difference???? how much of a pain in the butt is a stall?
