Post up your guesses!

761hp

725hp 640torque should be a pretty safe guess if we’re playing price is right style.. lol. That’s not knowing the dyno either, that would be a conservative dyno guess.

 

[Hemirunner]

We had great weather yesterday and with the humidity and rain today, not so much. I’ll post up the info later today.

775 HP 675 tq, dying to hear

Let’s see the sheet!!

I read through the thread, didn’t see where you divulged the full cam specs.

 

[Hemirunner]

Here you go. This was a lot of work. Improvement could be made but it’s a cost vs gain scenario when renting dyno time.

 

[68 HEMI GTS]

Can’t believe them heads are that good out of the box. What are the full cam specs?

270/274 .700 lift, 1.6 rockers, ground on a 110 in at 108(which I should have left at 110).

Looks like I was kinda close. Looks like it could be a 800hp pretty easy.

Yeah great guess. A solid 775 was my goal going in.

 

[69 GTX]

You hit it on the nail for sure.

 

[Hemirunner]

You hit it on the nail for sure.

Thanks. We were all happy with the combo. There’s still lots I’d do differently but in the end, it’s still a stock block build.

It wants more cam. It picked up pretty good with a tight lash. I knew I was on the small side but hit the target.

Can’t believe I left those out

Great numbers!!

I wouldn’t have been expected that.

What did you use for headers?

Thanks. They are a 2-1/8 dyno header with 16” long 4” collector. Kinda look like a sprint car header. The Superflow 901 dyno chassis doesn’t like the Mopar under chassis style headers.

I was very close on my guess. Hemirunner and I were chatting before the dyno results. Originally I guessed 820’s because I thought it was a 13-1 motor. But when he told me the CR I guessed high 780’s-low 790’s. I was pretty close. Very impressive time bomb build LOL.

Nice numbers for sure . Lose some hp going in car but still real nice .
I really have been happy with the 270s for the last 12 months i have been running them
