The 1.9s and some ported heads. Some nice lighter weight aftermarket springs and retainers. Would still sound and look stock. Bet it would run pretty strong and hurt some feels

I really don’t feel like doing a cam lol

Anyone know a price ?

yea and they would get the lift up close to .600 using the stock cam and make better use of those ported stock castings. I bet the gains would be even higher. Too bad they are so freaking expensive. Maybe SLP will drop a higher ratio stock style rocker like the did for the LS stuff.

LOL. That is ridiculous. You could build a 416 short block for that price. Hmmm, decisions decisions. I think not.

Thanks for the info, I was thinking the LS3 head was the best flowing around, but the LT1 head does flow more at higher lift. For some reason I am thinking the cam specs are the same, so I guess the increased power comes from the compression ratio?

Mind you, these are my ported heads and as far as I am tracking, they are both some of the highest flowing heads out there on a 28" bench. But when you put manifolds on the heads and flow them the LS3 manifold/TB on the head crushes the LT1 head with the manifold/TB attached.

The LS3 cam is 204/211 ICL is 120 and ECL is 115. I can't remember off the top of my head how that actually works out.

The LT1 cam is 200/207 116.5+7

The LT1 has almost a point more compression, DI, VVT, better heads from the factory with a manifold designed for tq and velocity. By better heads I mean 12* valve angle and splayed, reverse swirl pattern and a much more Oval/Square runner than the LS3. Remember, the best thing we could do with a head is make it a round tube that was straight. Everything from there is a compromise that looses efficiency. The best head so far has been the LS7. Mine flow into the 390's on my bench by .625" lift with a 272cc runner. The 2.20" valve doesn't hurt but it isn't the only reason the LS7 head is still king in my mind. Now, a LT1 head with a 2.20" valve on a 4.125" bore could be deadly. Hmmmmm, wonder how much it would be to put new seats in this head. The LS7 valves should be the same length.

Im depressed. I was excited about going that route. Could have been relatively cheap and easy to do and I think would run damn strong :(

Id still probably do a cam someday but it would be a nice next step for me...

My g6x3 cammed and tsp headed 2010 ls3 Camaro only made 505 rwhp through a manual. Had a 102/102 setup on it. 2 inch headers. UD pulley. It was a pretty aggressive build.

I know dynos vary but it seems like the average head/cam build the lt1 has about 50 hp on the ls3 from what ive seen. I know they have been in the 550 rwhp range as well but im just talking about on average the lt1 seems to make a lot better power with the average NA build.

Yeah, my LS3 H/C/I/E are usually between 500-520rw. But all of those motors were on pump gas. So subtract 25rw or so from these H/C builds we have been seeing on line lately and the gap shrinks. The rest is in the DCR bump and DI. The heads have a little to do with it as well.
