The mods i have already done are holley 350 and extractors. What other mods can be done to get max hp without spending to much money?

A 186 is a good thing for spirited street use, but for drag racing and burnout, a small stock block Chev will be cheaper and more reliable.

When they are naturally aspirated you can spend huge bucks on them for very little hp return (i know i worked up a 202) A much better option if yo

They ceased production about 12-18 months ago, and have no remaining stock. So you

Is it to be a street driven car or just a toy ? and 3. at the drags what group do you intend to race in ? Plus another thing
