I don't see a question in there, but that a/f is very very low for your setup

Ws6-dickie

Well just wondering if the numbers seem low

for street 13.0:1 is a good a/f ratio , maybe 12.5:1 for strip im guessing but yours is off if those #'s are accurate. stock is aprox 14.5:1

Dyno number sounds solid, but the only way to know is see what it traps at the track

Ws6-dickie

Car traps 113.31 hci2000ss

My bad...I just realized you have a small cam as well. Ok that trap speed tells me that you are making more than 349 rwhp on a full weight car. 113-115 sounds about right to me given your mods, and being full weight

Well when i went to the track i had the ls6 intake and tr55 plugs in also dyno was on a mustang dyno if it matters any im hopeing with the new 1 7/8 headers and ported 243s to be close to mid 400 whp

Always depends on the dyno but 400 rwhp should be easy with those mods

Ws6-dickie

Id really like 450 or atlest to hit mid to low 11s on motor

You like the drivability of that cam ? Im about to order that same cam 😀

Once you install your heads, long tubes and get it tuned 11s should be easy.

You should be able to get low 12's out of it now, depending on your 60' and air quality.

Ws6-dickie

60s were **** best was 2.2 out of 2 runs i got last year i have some toyo dr's now but have to wait till april to run again

Ws6-dickie

It drives ok better if it was tuned id say it has some bucking betweeb 1400 1700 rpm but i feel like the car could pull better up top im thinking of doing something bigger when i do the heads

bisscrac

Are you just on a stock tune right now ? Or a mail order tune ?

Ws6-dickie

Pretty sure there is some kinda tune but it runs extremely rich so whatever was done is not rite

bisscrac

I bet with a tune your numbers would be a lot closer to what it was you were expecting
