This is not on my sig truck, helping a buddy out with his fun truck.

98 12 valve, 4.10 gears, heavy flat bed, 4wd, stock DVs, stock injectors, no plate, star wheel full forward, now a super b special, timing at 17.5 degrees, heads bolts re-torqued.

put a super B on, gauges, re-torqued the head for him, now it seems doggy off the line. yall think its under-fueled or is the timing too far advanced? no GSK and stock fueling system. I played with the starwheel (he had already pulled the plate) and it ran the best with the starwheel cranked. toyed with the idea of doin the afc mods, but he thinks i went too far with the timing.

input?

thanks!

 

way underfueled in my opinion. gsk n injectors n that thing will come alive

 

mega underfueled

 

That set up would work well with a regular Super B, but a Super B Special needs more to run it. That is a good timing setting for a real world truck.

 

Yep, under fueled.

 

WWWWWWWWWWWWWAYYYYYYYYYYYYYYY under fueled. i would go 181 dv's...5x14's....and 4k gsk and 60lb springs....she be a monster then... till he blows the trans out onto the road

 

if he dosent wanna spend the money on injectors, dvs and everything he can sell me the turbo

 

That truck is not under fueled for a super b. If its a superb special then yes it is underfueled. A super b is only a 57/65/12 if memory serves me right. A special is a 64/71/14. A super b is not much bigger than a stock charger.

 

a b isnt bigger then stock just finned diff on compressor side

 

super b special is 64/71/14
