Obviously a popular topic here, lots of good info and shared experience , including that last link to more great experience shared by Jim Hand

I am also uncertain if I'd like the Rhoades lifters (restored stock looking gto convert), but I'd really like to hear them in person if there's anyone in central/eastern MA , southern NH that is running them ? Maybe I could catch up with them at an event somewhere over the summer
On the other hand, (and seemingly supported by that last Jim Hand article linked), I may not absolutely need the variable lifters if I were to switch to an 041 style cam, since I have a manual trans and manual brakes ? (currently I have 14" vac @ idle)
So I'm also wondering if anyone uses an 041 in a 455 with standard lifters , and with 1.65 or 1.5 rockers ?
I guess at 9.4 I could use an 041 cam, but if I wasn't planning to try the Rhoades lifters, what option might I have ?
It's obvious that the Rhoades with certain cams (041 etc) are a proven performer, but what about HFT options with standard lifters ?
My current "plan B" (if dissatisfied with the xe274), was/is the crower 60243 , but I'm not sure how much of a difference I would experience or if it would be worth it

Here is my experience with the XE274 cam. Engine is a 455 40 over, 1.65 rockers, 6X heads that have been milled 20. Compression is at 9.2.The heads got the Jim Hand porting at home, but I only did the bowl work and did not touch the ports. 32 deg total timing all in at 3k. Th350, Continental "J.Hand" converter with 3.89 rear. 750 Holley on a Torker 2. 275/50/15 MT drag radials. Weight of the car is 3880 and ran a 13.04 in the 1/4 when launching at 1800. with a 1.8 60 ft. I'm sure i can get a better 60ft.
