any one know of bolt-ons for a speed density 302. i have been told that the majority of after market parts are produced for the more popular mass air engines and will not work right on my speed density motor? any thoughts?

 

convert to mass-air

 

ok how? not even sure how speed density works. truck runs perfect and has good power just thought i'd make it a little more fun. but if i have to rework the fuel or electrical systems... i'm out.

 

There is alot of things you can do with SD with out going mass air you might do a search in the 302/351 engine forum.
