As it is it certs to 9.99. The 10 point is a lot better at keeping you safe lol. 6 points are useless imo. Always going to want to go faster.

Couple of other guys that went said the same thing. No traction.

Too bad because the weather was good. They'll get it. Just kinda wasted my once per year track visit but the owners treated me good

How much for it?

If you only go once per year, do you really want to cage it and make your backseat un-useable?

I'm debating this right now with my Camaro.

Incredible results for such a small cam. 135 mph in a 9" F-body and a smaller cam than many C6Z's out there only making 550whp!

I really expected to see the power flatten off and plateu more upstairs. Interesting that it has a well defined peak and fall-off. Time for MORE CAM!!!

Nice!

The 40mph tail wind helps too.

Congrats Big Hammer! I know those numbers far exceeded your expectations. All I can say is those MAST heads have me sold. With the right cam and intake, those may be the best LS3 heads on the market.

Bolt on Ls6's are all the rage

I'd love to hit 9's NA in my street car someday... they're not going to let me do that without a cage. I don't use the back seat anyway plus it'll
Probably help stiffen up the chassis

Thanks!

Yeah I was floored lol. So was the dyno guy. I put a lot of research in it though. IMO ls3 heads really respond to bore and RPM. With some fine tuning I'd love to get closer to 140 mph. The car is an absolute blast!

The mast ls3 heads looked great on paper to me, but I've never seen anyone use them to their portential yet. They're beautiful heads

Im torn on a bigger cam... it runs nice and the drivability is still there. We originally spec'd it for a stock ls3 bottom. I'm also starting to get a little plenum vacuum around 7650+. If a guy wanted to though he could go to a bigger cam and the fast race runners and spin it to 8000-8300 pretty easy

That is the trade off for sure. Enjoying driving the car is huge in my book. But, with that said, you could get more power an move the peak up 2 or 3 hundred RPM without hurting drivability too much.

I think so too. At that point I'll be looking at my intake tract as well. Go up to 105mm, port it all out and rig up a ram air

105 throttle and port matching the intake neck should help some with that high RPM vacuum you were starting to see. if you're thinking of the holley 105, I don't think it's tapered. Might be added benefit to adding a taper to it?

Although I have to LOL. We are nitpicking a really phenomenal engine. It's like watching head to head when they nitpick the McLaren P1 and Porsche 918.

For sure. It rolls out and will do nothi g but go faster with some chassis adjusting

Holley has two versions. Tapered and not tapered. If anyone is looking for a Holley I'm a dealer and can get it a bit cheaper than most places. Just hit me up.

That's good to know!
