Hey im finally back.

my setup finally got dyno'd
-350 from 69 camaro bored 0.030 0ver
-rpm airgap intake manifold
-compcams xe262h cam
-edelbrock thunderseries 650
-holley red electric fuel pump

When I had it on the dyno, I tried an 8% richer rod, and three different acc. pump stages and nothing would solve the off the line fuel reqirement.

With all of these mods and the not enough initial fuel shot, I managed 330hp@ 5100rpm
and 350 ftrq@4800.
**I didnt rev past 5100 but it seemed like the cam was dropping off so i didnt want to rev further**

As soon as I can sell my 650 edelbrock and get the holley 650 double pumper I will have my initial fuel requirement met and hope for better performance with a possible 30-40hp increase.

The dyno numbers were reached with 2 pulls consisting of minor initial timing changes..plus 89 octane fuel and a small 10" air filter

 

I`m guessing you were using an engine dyno.You might see 350hp with a better carb.1hp per cubic inch is a respectable
goal.Did you advance your cam 4* or is it ground 4* advanced?

 

the comp cams are ground 4* advance out of the factory but initially with my old setup (edelbrock EPS, old distributor) I installed it an extra 4* advance with the impression that low rpm power will be plentiful.. RESULT..100% WRONG.
THerefor because I had to change the crappy old tranny I thought why not take the trans. and and engine out, only a 2 days job so I did. In the process I changed the intake to an rpm air gap and I installed the cam at 0*.
THats how I got my decent dyno #'s , even with insufficient initial fuel shot(hurts 60ft badly) and using 89 octane, and small 10" filter.

thanks for the reply, I look forward for more

 

Did you try a larger accel pump squirter nozzle?

actually i didnt. I know that is what i need, but I haven't seen one in the edelbrock catalog but i will check again.If I find one Il try it out and save myself the purchase of another carb.

hey 305 sbc, are you putting out 440 hp to the wheels???
if so tell me your setup, maybe I could learn a few tricks from you.
Thanks

 

Yes Edelbrock makes bigger squirters. Look at the number stamped on the top of the squirter. I swapped mine to a #43 (see pic).
There's some info about my old engine on page 18 of my site. It's 440 rwhp.
