Pontiac Larry..... Do you mean "out perform" as from a performance standpoint as in horsepower production capability and better track performance ? Or only out perforam as in better driveability?

Bret..... what are the specs for those two cams you like. Valve lift means very little in comparision.

Steve...the engle is in the low 290 deg advertised area... i believe 106 lobe sep... the ultradyne is roughly the same.... im not near the cam card, or i would give the the specifics on the UDyne... My Dad bought the engle when i was very young.... who knows what happened to that card. Im making tons of torque with both of these cams and driveability is excellent... havent had them in a 400... but im guessing they would work just the same with the powerband moving up a tiny bit.

I mean both Steve, I personally ran as quick as 12.1 (7.7 1/8th) spinning dry cracked 26x10 ET's with a 3.23 geared 80 Formula true beater street car in 2003 that had a 14 yr old stock rod 455, iron Dport,iron intake,qjet,11" 2800 stall , I had built in 1989 that had been runnings 11-12 sec ET's for the whole time. Just getting the heads ported and new rings would have it in the 11's all day long. In a race car application you could go faster. Seen XE274's in fairly radical setups hitting a wall in the 11.9-12.1 range as the best performing ones and other not out of low 13's.

Yhen you tried both cams in the same or VERY similar set up regarding engine and chassis ?

I never ran the XE myself just seen many many threads on here and a few people I know as well(I am not interested in wasting my money on one). The guy with buick wagon (full drag car) is dialed in real good , hitting hard a barely gets 11's. I will say a similar cam and gear swap that is comparable when a buddy had his 455 powered 79 TA at the 1/8th mile track. He had 2.73's and a Summit 2801 224/234 114 and ran 8.3 , switched to a lunati 230/230 110 and 3.23's ran rougher , drank gas , more rev's on highway and it still ran 8.3 but lost on all positive aspects(economy,driveability,etc) .
