Hope you get that , I did not get close to that with the big mouth heads , but was runnning a stupid Air Gap intake ported but not enough , with your intake you should get much more than I did . would really like to find an intake like yours

What cam did you use? Just curious, gotta upgrade my HR cam this Season.....

It was custom grind from Hughes engines. Off top of my head it’s like .580 hydraulic roller on a 103 lobe separation. 235ish duration.

hm...if you get the cam Card can you please post the data? don´t think they put in a 103 LSA with EFI....but you´ll never know ;-)

They don’t. This cam was ground for the old combination I had which was stock stroke 340 with ported iron heads. But ultimately I never had enough compression for the cam. So when I switched pistons I also went for the stroker kit. When I emailed Dave Hughes and asked about the cam he said he would gladly sell me a new one, but to quote “try that one out first”.
It runs its *** off. I daily a hellcat and my *** dunno tells me it’s comparable. Not powerwise but the barracuda is a lot lighter than a hellcat.
but yes a wider LSA helps with vacuum which FI likes.

I drove the other day just to get a feel for it. It rips pretty good. Took some manual adjusting to get the idle right but so far so good. Starts right up and it’s constantly learning. It’s still cold here in Maryland so won’t go down the track for some time
here are the specs on my cam

I USED the 426 cause i did not want to use one of my 1970 340 blocks 360's are cheap

best roller lobes his inverse roller profiles cannot be approached by other grinders using a big grinding wheel
What pistons you using? I had to order new pistons to raise the compression , the 23cc dish and 10.5 was not enough compression so I bought some 13cc dish pistons to raise compression a bit . just waiting to install them
