what type of changes can you do to speed density without messing it up. can you do a throttle body,cold air,heads. i know if you change cam its hard to dial in..any info will be helpful..

you should be fine with those changes, if changing the cam, stay with one on/around a 114 LSA and or one that won't affect vaccum signal that much

what do you mean by LSA 114..what size of throttle body,what type of heads

JPJP

You may use any type of head or intake size. You may also supercharge (my '86 S.D. is supercharged). You are limited in type of cam however.

how does yours run and what have you done to it thanks for all help mine seems to be stock but it seemd to pull better than my 93 lx did with bored to 306 and cold air,throttle body.the 89 seems to run faster to me..thanks for all the help.

The engine is all stock. SN Paxton supercharger and ported intakes with 65MM throttle body. That's it for the engine. I just recommend a MSD ignition to keep the spark hot.
