i currently have a stock l98 with 80,000 miles. i want to spray it but dont know how big i should go with the stock internals. any advice will be great.

 

kit i have is a discontinued NOS kit and it was made for a stock 305 or 350. it was 110 for 305 and 150 for 350.

 

i was thinking 100-150. will i have to upgrade my fuel pump. i know i have to retard the timing but is there anything else i need to do.

 

i havent on my 305 with a 110 shot, the directions dont even say to retard the timing. the instructions for it say with different jets its a 150 shot for a bone stock 350 with stock timing and plugs.

ive been running the 110 shot on mine for quite a while with no retarding and stock plugs and its been fine. the motor looked great when i pulled the heads to have them ported, polished and rebuilt.

 

Scheister any chance I can get you to post the jet chart for that kit? I've got the same kit minus the bottle on my car.

 

I just sent you an email with the old 5151 instructions attached.

Cheers!

Email recieved, much appreciated. This isn't the kit I have but it gives me a general idea of where I'm at. One question, is the jet rating for a pair of jets firing into twin nozzles? Mine's a single jetted spray bar in a sandwich style plate (may be an LT1 setup but it came off of an L98 Camaro). I'll have to check but I believe I had a 57 and a 36 jet in there and that combo works unreal.

 

Yes, on my setup the jet sizes are for a pair of jets firing into twin nozzles (two N2O pills, two fuel pills).

Is this your setup?
