Hello all I'm asking for advise here is my combo
1968 440 stock short block
Trick flow 240 heads
Mancini rocker arm 1.5
Comp cams XE290S intake lift .540 ext .558 290 intake 298 ext duration
TTi headers
3500 stall
391 gears
In a 71 scamp
Now my questions 1. can I run 1.6 rockers and will I have any issues
I think it will bump the lift up to .576 int .595 ext
I'm concerned with the ext lift hitting piston...
