im getting ready to fire up my 355.
time now has come to setting up the carb. i need a little help on where i should start with jets, as this motor is a little more powerful than my practically stock 350.

combo is,
355
10:1 cr
lunati voodoo hyd roller 60122 535/550 231/239 110/106
brodix ik 180 heads, 64cc
holley 300-36 intake
holley 3310 750 vac sec.
holley 130 gph mech. fuel pump, and regulator.
right now a 4 hole 1" spacer will be used but i also have a 1 hole.
1 5/8" headers, 2.5" x-pipe with moroso race mufflers and 2.5" tails.


i was thinking somewhere around -74 jets to start, but do you think that would be too lean? would upping the accel. pump to a 50cc benefit much?



thanks

I would start at 70's in the primarys first...then convert the 4160 to 4150 and go with 80's in the rear. Should be a good starting place.

where in the 70's should i start at? at 70, or higher up say 74 or 76?

i plan on converting the rear over.

thanks,

i have 68's in the front now and stock plate in rear.

came from the factory with 70's in the front. im thinking with 430hp that 70's might be a tad lean.

i dont want to burn a hole in the piston the first 5 min of break in.


thanks.

o re-read dirts posts and realised he was talking about 70, not 70-79 sizes.

maybe i could start there or a tad bigger.
