Recent gen3 guys with asa or howards asa cam come inside
I want to hear from recent builds with the gm asa and/or the howards asa cam. Mods, dyno sheets, track times etc. Gen3 guys only...ill post a sep thread in the gen4 forum.
Post up and if you have an actual GM asa cam card please post a pic!
02 LS1 6 speed stock engine with high miles. K&N cold air intake, Speed Engineering headers with 1 3/4 primaries with 3" collectors and 3" true duals with generic single chamber mufflers no cats. Howard's ASA cam with LS3 valve springs. Deleted the PCV totally. No air injection into the exhaust. No EGR or any of that junk.
Made 404 hp, 385 torque to the wheels on a Dynojet.
I’m putting my 6.0 L76 back together from a lifter failure. I have again went with the Howard’s ASA cam for it except with a 113 LSA instead of the 110 I put in the LS1 Camaro. I’ll post it once it’s done and back in my Pontiac G8. It’s a Gen 4 with rectangle port heads so I’m interested to see what it’ll do.
Not to shabby. Is that an auto or manual trans? How’s does it drive down the highway? It almost looks like it could have a few more rpms in it.
I would love to see the exact same car try it with the GMPP cam and Howard’s cam just to see the difference on the dyno and the street.
It's a T56. It drives very well, no bucking at all above 1300rpm. I'll probably spin it to 6500 when I go to the track. I changed the exhaust to Hooker Blackheart 1-7/8 longtubes and their 2.5" over-axle true duals. I need to get the retune still. Probably choked it down a bit, but the dumps were getting old. Gonna get a full retune on the dyno with the new exhaust.
You should consider some cut outs for it. My buddy that bought the Camaro from me took my 3” dumped exhaust off and put in a 2.5” over axle set up and it just choked it bad. Car lost so much power. I bet it sounds really good thought. If it’s a cat back it probably won’t loose that much power compared to my buddy’s butchered exhaust shop almost crimped the pipe going over the axle. He eventually went back to my dumped exhaust set up. Any video clips?
The Hooker Blackheart system is very high quality IMO. 304 stainless, full mandrel bends, 100% fitment with no required additional pieces or modifications. I'm very happy with the fitment and sound. We'll see what the power ends up at when I get it back to the same Dyno.
My pushrods are stock diameter (can't think of what it is), but they are 7.425 instead of the stock 7.4. I don't remember why I went with longer, but I do have a pushrod measurement tool, so I'd imagine that's what my average measurement came out to. No valvetrain tapping.
