i have a set of edelbrock shorties, a comp cam extreme energy cam 12-249-4 with .434 lift intake .444 exhaust and 206/212 deg at .05 this is on a 112 lsa and a holley tbi intake with the 670 on top with 65pph's in it. all on a 350. it has about as much guts as my 215,000 stock lo5 had. i can barly burn my peg leger

 

no one hase a clue hu bummer

 

Have you tuned it?

 

no i did some plug readings and there is no thing on them ley look bran new after 1600 miles a bit tan but no black no glaz and no white

 

With those mods you definitely need tuning! No doubt about it! I wouldn't be suprised if you would pick up 50 hp by doing some dyno tuning.

 

maybe the plugs dont show cuz i havent run it hard enough. still sort of braking it in. it would be nice to get 280 hp out of the thing that way i can keep up with new 5.3L chevy trucks with my 6000 pound beast

 

This is what tuning can do for you.
