I have a holley single plane and 750 carter purchasing a Richmond 373 posi and these heads have lots of work they were on a 283 nitros motor the tires are 235/55r15 in rear fronts are 195/65r14 headers are headmen hears 1 1/4 because is a s10 1989 for clearance I want a lopy sound with power and go hyway miles that why I figured gi with this beffy 700r trans
OK...I THINK YOU HAVE THE POWER PACK HEADS...ANY WAY THE 283 PUNCHED OUT TO A 292 WITH 10 TO 1 COMP IS/WAS THE 1 0F 2 FASTEST MOTERS IVE EVER RUN AND IVE RUN A FEW..NOW I RUN 8.90S ON THE STREET WITH A BIG BLOCK OK A 496CI..13.5 TO 1 BUT HAVE EVERTHING SET UP JUST RIGHT TO WHERE I CAN RUN 92..IF I DONT GET ON IT... ****CALL UP HERBERT CAMS AND ASK THEM FOR A 30-30 GRIND FOR THE 350..THEY WILL ADJUST FOR YOUR COMPRESSION..AND RUN A SOID GRIND OR YOU WISH YOU HAD DOWN THE ROAD...WITH TODAYS ROLLER ROCKERS AND STUD GIRDLES...YOU CAN GET AWAY FROM ADJUSTING THEM ALL THE TIME...WHEN YOU DO ITS EASY EOIC TO ADJ...
PS..WHEN YOUR DONE ILL SEND YOU THE DIST.CURVE ..ALSO TRY TO FIND OUT IF THE HEADS HAVE BEEN MILLED???/OR CHECK YOUR EXH VALE CLEARANCE WITH SOME CLAY AND SEE WHAT YOU HAVE..TIME TO HAVE SOME FUN AND ITS REALLY EASY AND INEXPENSIVE TO DO THESE THINGS..
