doing a 383 for a pulling truck.

i have a set of .030 trw dome l2293 pistons and need to know what to cut the block for. want to be in the 12.5-13.1 and will be running VP110 or sunco 112.

what deck height do i want for a stock stroke and rod length motor with a cam around .550 lift and minimum fly cutting on the pistons. heads are 915 with 2.14/1.81 valves

You ned to check the cylinder heads for what size CC they are now and then decide what deck hieght is needed for the compression ratio you want along with what CC head gaskets you need also I would mock the motor up wth one piston and the cam and lifters and set the lobe seperation timing where I wanted it and then check the piston to valve clearances to see if the pistons need clearancing or not and then do the math to get the deck hieght cut where you want them
