I've resealed %26amp; cleaned the oil pan, put a new oil pump, changed the timing belt, resealed %26amp; cleaned the intake manifold, and a few other tune ups.
What should I do to get some more horsepower out of this engine?
My budget is about $500 for parts.How much horsepower can I get out of a 1990Chevy 305 TBI? And How?A $500 budget is tough to work with but here is a big hp boost combination if you can go up to about $725.
Crane HI-6S Multi-Spark Ignition (Part Number: 6000-6302) $191.99

Crane cam (Grind Number: HR-284-2S-12 IG) $319.95 plus about $25 for a cam change gasket set

And then if you can scrape up another $114.71, to bring it all together and get 'almost' the most horsepower available, I suggest you add a JET Stage 2 Performance Chip (Part #: 19010S)

I said %26quot;almost%26quot; the most horsepower available because after the mods it would be better to take your car to a speed shop and get a dyno tuned custom burn chip specific for your setup. But that alone would cost nearly $500, so the JET Stage 2 Performance Chip is your next best option.How much horsepower can I get out of a 1990Chevy 305 TBI? And How?try an after market air filter like k%26amp; n 50 bucks and true dual exhaust system maybe some good glass packs or cheap flowmaster from 180 to 400 bucks. there is also a tornado which is supposed to help with air mixture about 40 bucks and a throttle body spacer that could help with air fuel mixture also about 50 to 100 bucks depending on which one. the difference is small individually but does help,How much horsepower can I get out of a 1990Chevy 305 TBI? And How?get a 750 holley and a manifold and two 2.5'' exhausts.
Chev motors don't have timing belts they have a timming chain.Try a NOX system.
