Nice numbers. I'm giong to be putting in a 224/230 on 114 here soon. Who tuned it for you? Auto or manual?

 

street tuned locally...m6 tranny

 

What does a stock LT1 dyno at the wheels?

 

stock lt1's dyno in the 230-250 range...i did 250hp 291tq with knn cai, and flowmaster exhaust...

 

I have an iron headed lt1. Will it make much of a difference? This isnt in a caprice or impalla, its in a fiero with a full 2.5" exhaust into an 80 series, with all emmisions crap removed. Is it possible for this set-up to hit 280 at the flywheel? I was told I MIGHT see closer to 300, but im not sure. At the fly that is.

 

I did 272 HP/300 TQ, stock M6 with only a CAI.

 

made 348/344 with stock heads with CC306.
I think your numbers are little low. Is everythiing running ok?

How much did the shop charge you for the porting?

Nice numbers

 

the iron headed LT1 might do even better considering the heads flow better stock.

 

were those SAE corrected?

 

stock as in, not ported? I'm thinking of upgrading to a bigger cam, how's the driveablity of the cc306? Is yoru car a daily driver?

 

Numbers look ok, but a little low. See sig.

How much head work did you have done??? Did you get them flowed?? I'm willing to bet that's what's holding you back, especially since you're running Hooker LT's. My numbers were through ASM headers and a Random Tech cat too, so looking at yours I'm definitely led to thing they're a little low. Still respectable though!!

 

i made 356rwhp/349rwtq with the 224/230 and lloyds port job.
and that was with a failing fuel pump, very lean up top around 14.5 at 6500

see sig for times

Now that I'm leaning towards some heads I hope this cam works out great for me. Their is some pretty proven numbers here.
