this combo works well and increases the dwell time of the piston at TDC.Young Angus said:I found out today from the original owner of my new coupe that he thinks the guys who did his engine put 302 con rods on the 351 clevo thats in it for some reason to increase something...what would this be?

According to ACL, 302C rods are 12 grams heavier than the 351C rods.davis said:Yeah? By how much?
What was your "before" piston weight and "after" piston weight? Also, what of the differences in weight of the rods themselves?
I can just see it now! The minister says to the groom "You may kiss the bride" and he leans forward to give her a big pash but all his teeth fall out after the ride to the service in your teeth chattering Cobra replica. Man that cam is big enough to rattle anyones teeth!gus351 said:hey xw383,
My weekender is an AC Cobra replica. Nearly 5 yr project. Just got to do paint and have the interior trimmed. Should be ready to register in February. It had better be as i have been asked to drive one of my mates to his wedding in it! Engine/trans specs are as follows, from a previous thread.
Tell me about the XW, i had an XY a few years years ago and love those two models most.
I USED 6" 302 RODS IN A 351C WITH CROW 212 +224 @50" CAM AND 750 VAC HOLLEY, EDELBROCK PERFORMER MANIFOLD, BACK YARD PORTED HEADS,IN A XE FALCON WITH 2500 STALL AND 3.5 GEARS THAT RAN [email protected] REVED TO 5200rpm AND I SHIFTED AT 5000rpm. THEN I PUT IT IN A 1800kg F100 WITH SAME GEARS AND STALL AND TOOK IT IN NARROGIN BURNOUT COMP WITH THE CROWD ASKING FOR MORE.gus351 said:As Davis suggested, i think this may open up the old debate of long vs. short rods.
I use 6.250 rods and Ross custom pistons, not because of weight, but because they give the engine characteristics i want.
I drive a car with a wheelbase 16 inches shorter than a Hyundai Excel and wanted more mid range and top end power than stump pulling torque at 1500rpm.
I dont understand which way you are voting.aussie7mains said:From my experience of 302 rods vs 351 there was a noticable improvement in the spread of torque from a 351 with ported 2v heads. As far as I'm concerned all the dwell time etc etc is BS. If you do the calculations the difference is so slight that you wouldn't see it with the naked eye. Overall I cant say why there's a difference, but there is! A7m
How does the 302 rod improve torque? If its not the dwell thingy, what give the improvement?aussie7mains said:Oh, im in favour of the long rods for any type of 351c use. They seem to work particularly well with the 2v head ports, I could notice the difference in the Spread of torque, not the quantity, which made the car easier to get allow with.
However i wouldnt bother doing it UNLESS I was doing a rebuild and it wasnt going to cost much to do. I dont think the difference warrants a tear down just for that.
