Pushrod and Engine Questions?

i just had a couple questions before i put everything back together... my setup is: F cam, stock 302 bottom end with TFS pistons, TW heads, and FRPP roller lifters. now will i have any problems running 6.75" pushrods which were recommended to me by a couple guys online? also will i be able to get away with my 1.72 Scorpion roller rockers or will i have to use 1.6RR? now if it is possible can i do a step up system with 1.6 intake and 1.7 exhaust? thanks in advance for any help!

Yes.. it is an old trick to get more lift from the larger rocker ratio!! On the exhaust the F cam will teck out something like this...512 intake and .544 exhaust!!

so you think with the 6.75" pushrods and the step up RR i wont have any clearance issues? thanks!

Push rods NEED to be the correct length for the rocker geomerty !!! AFTER the correct geomerty for the rockers is obtained.. THEN check the P/V issues!! you HAVE to have the push rod length correct.. cant play with that...cool??
