Apologies for the thread derail.
Regarding Comp stuff, why is that? Hardening? Ground for smaller tappets? Poor quality control? Poor customer service? I am not trying to be a smart ***, I'd just like to know because I am considering one of the following cams for a 1991 hydraulic roller LA360 build I am working on, shooting for a 9.5:1 compression with machining block and possibly the heads, pistons, and gaskets.
Lunati 20200712
Voodoo Retro-Fit Hydraulic Roller Cam - Chrysler 273-360 282/290 - Lunati Power
Requires 2800 stall
This will most likely require a new torque converter, as my current TC is a 2400 stall
XR274HR-10
20-811-9 - Xtreme Energy™ Retro-Fit Hydraulic Roller Camshafts
requires 2000 stall, and I can get away with a 9:1 compression
I can keep my current 2400 TC
XR280HR-10
20-812-9 - Xtreme Energy™ Retro-Fit Hydraulic Roller Camshafts
requires 2500 stall
Maybe I can squeak by with my current TC 2400 stall.
As it stands with the above three, I am kinda leaning towards the Lunati, and will eat a lot of Ramen, peanutbutter and oatmeal and spend that few hundred grocery bucks on a new TC.
I know I will have to go with new springs no matter what I get, even if I decide to just go with a mechanical flat tappet which I would actually prefer, since I really dislike the large mass hydraulic roller lifters when compared to mechanicals, which require lighter springs. (It looks like I'm going to want to talk to AJ about some math regarding speeds, gearing, tire size, HP, and rpm at the traps, and I've been procrastinating on that, heh).
