Just out of curiosity, which UD Hydraulic roller would compare performance wise with the famous solid lifter (non roller)UD 288/296?

bb427 Nov 1st, 03, 2:07 PM what I have now is the UD hyd roller 288/296 234 242@.050 .600 .600 on a 110 LSA how many degrees more would I have to go to be comparable to the performance of the solid lifter (non roller) 288/296 cam? bb427 Nov 2nd, 03, 5:25 PM Anyone? How many more degrees will it take to get me to go even better than I am now. To compare to that famous cam? (288/296 solid) Don’t get me wrong the car will do upper 11s but you always wonder what will give you more. Wish I would have went bigger first time. Here is the specs (new this year) 60 over 427 215 oval ports (219/188)&ported JE forged pistons 10.25-1 cr UD hyd roller 288/296 234-242 .600 .600 on a 110 lsa Matching springs CC roller lifters Crane roller rockers Cloyes hex adjust timing set Performer RPM intake 1/2 four hole spacer 750 DP holley k&N air filter Holley fuel pump Mallory IGN Dynomax headers 3''exhaust with flowmasters Turbo 350 - 3000 b&m stall 410 12 bolt posi 3750 pounds with driver Could someone please give me a HP Guess, or a Desk top dyno on my combo? Thank you. UDHarold Nov 2nd, 03, 9:53 PM bb427, You would need a 296/302HR with 244/250 at .050 to come close to the 288/296F10 at .200. The 308HR that I have, with 255 at .050 and .650 valve lift, is a much bigger cam, with 175° at .200, 9° more than the 288/296F10's intake. The 296/302HR would not be an identical swap, but close. It would have a little less bottom-end, and as much or more top-end. I doubt if it will really turn 7500, though. UDHarold | ||
