i found these on summit's website: Rocker Arm, Stud Mount, Roller Tip, Steel, 1.6 Ratio, Fits 3/8 in. Stud, AMC/Chevy, Small Block. there 10.95 a piece and i was wondering if i can use them for both the intake and exhaust?

 

[mkiiisupra]

yes, they work on either intake or exhaust

i was reading a book on sbc's and it says you can use a 350 crank in a 307 sbc but only if you bore it out to 4.00 and use 350 pistons, why is that?

i was reading a book on sbc's and it says you can use a 350 crank in a 307 sbc but only if you bore it out to 4.00 and use 350 pistons, why is that?

Because it allows you to use the right compression height pistons for a stock application. If you use 307 pistons on a crank that has roughly 1/4 in more stroke, it will push the piston out the top of the bore. However, if you can bore a 307 block that far out (seems like a stretch...), you could just use the crank it comes with to get a 327 instead by using 327 pistons. Remember that a 307 is a 283 block with a 327 crank.
