Hittin the Dyno

[blown65]

Did a few changes to my motor.

Ported the heads by Duane Busch, new springs, tit retainers, valve job, decked the heads to gain some compression also.
New Cam that he felt would work better for me.
Converter is off to UCC to change the stall speed. Probably around 6000-6500.
Added a GZ Vac Pump to the system also
Super Vic in place of my victor jr.

Hoping to pick up a fair amount of HP and be deep in the 10's this yr.

Should see the dyno by thurs if all goes right. Going to try out some Q16 VP fuel too.


532hp 450-460tq before. Hoping for something 600+hp and close to 500tq.

keep us updated.

All bolted on ready to go.

Couldn't use my headers, so stuck with their 1 5/8" street rod ones.

Ran good, 605hp at 7600 and 468tq. Q16 picked up about 15hp over the Torco 114.

Nice numbers!!!

I watched some of your video's, your car runs real good.

NICE!!!!
recent engine pics?

Prob shift around 8300 or so. Gotta fix or replace the pop off valve for the vacuum pump though, the nut keeps turning and dropping the vacuum.

A thing of beauty!
Right before he let off the throttle it sounds like there was a dip in the rpm, what caused that?

 

[blown65]

Might be the dyno software, it was set to stop the pull at 8000 rpm so I'd assume it would load up to keep it from keeping to rev.

 

[iskwezm]

thing sounds nasty.............very nice

 

[blown65]

Alright, where's the blower? I assumed with your moniker than it was a blown 347 although the peak rpm had me wondering...now i'm really impressed!



Where can I find you engine specs?

LOL, I used to run a 6-71 blower quite a long time ago. Its just N/A, no power adders.

Few yrs down the road I still plan to go back to a power adder, probably a turbo of some sort. This will be fun for a while.

Solid roller 700 lift, ported vic jr heads, port match super vic, 950hp ProSystems carb, R302 block, Scat crank, hbeam rods, JE 13.9cc domed pistons (59cc chambers on the heads so right at 14-1 compression) Ran on Torco 114 and also Q16 (116 octane)

Wow! I was under the impression it was a blower motor as well. You are doing very well for a high compression NA motor. My NA 347 will never make that kind of power.

NICE!!!!

Dont have any but these, its still it at the engine shop.

 

[blown65]

back in the car ready for action. Still got a little more cleanup to do, just got done washing the outside. Sounds soooo good. heh

 

[fastcoupe68]

Sounds awesome! Good luck with it. Can I ask what vacum pump system are you running?

ya, its a 8.2 deck 370 cu inch sporting TEA TFS ported Hi-ports and an AOD. Its not setup for drag racing, really tight converter but still turned 11.20's at 123mph with a crappy 1.85 60. 1st gear takes forever since that motor shifts at 8300.

Otherwise its a pretty much stock 67 GT350

Just got back from the track. Not much traction off the line, no prep but still did pretty good. Has quite a bit left since I'm spinning pretty hard. Hopefully next outing they will have more rubber down.
