Almost Done - Pontiac Trans Am Engine Swap Part 10 357 V8 Street Demon Carb
This is Part 10 of our 1987 Pontiac Trans Am engine swap series. We've been swapping in a carbed 357 small block in place of the original 305 TPI. Since the last video, we installed the distributor, plugs, and wires. We also plumbed in the temporary fuel setup with a Mallory 4309 Regulator. Then, I painted the factory valve covers and tightened up the belts. We only have a few more things to get done before we can fire this engine up for the first time. I hope you find the videos interesting...thanks for watching!
New Parts - Pontiac Trans Am Engine Swap Part 6 357 V8 Street Demon Carb
This is the sixth part in our 1987 Pontiac Trans Am engine swap series. Today, we received some new parts in the mail and we thought you might like to see them. We got our 625 cfm Street Demon Carb, a Chrome Demon Air Cleaner assembly, and a Mallory 4309 3 port fuel regulator. We're really getting anxious to get it all put together. Thanks for watching along, we appreciate it!

It's Alive !!! Trans Am Engine Swap Part 12 - 357 V8 Street Demon Carb 1987 Pontiac TA
The Trans Am is finally running again. The engine is sounding really nice. Just have a few more things to button up before we can take a little test drive. The main thing holding us back at the moment is the Throttle Valve Cable for the trans. I need to get it properly set up before we can drive it. It feels good just to hear it run well though. Thanks for watching along, we appreciate it. There will still be many more videos to come in this engine swap series, as well as more vids on restoring/modifying the Trans Am in other ways.

Pontiac Trans Am Engine Swap Part 11 - Fuel Pump Choke and Fans
This should be the last video before we start the car. Today, or plan is to fire it up for the first time. For those who haven't been following along...my son and I are swapping in a carbed 357 in place of the original TPI 305. It has been a fun project so far, with only a couple minor issues to this point. Thanks for watching, we appreciate it!
Dyno 5.3 Home Ported Heads '84 Chevy C10 LS6 Cam 4L80E Truck
Check out my other videos like this on the link below:

I finally got the truck on the Dyno (4 Jan 13) for the "After" Dyno. After the home ported heads and a tune on my 5.3 with LS6 cam through a 4L80E.
There are a couple variables of course (always are). For one the weather was the complete opposite as it was the first time. A lot cooler. Around 55 instead of the 100+. Another is that this was with the tune adjustment. We dont know how lean it was on the first run before the heads.
Either way, the truck put down respectable numbers with a baby LS6 cam and the 80e trans. It had an increase of 47rwhp and 55 ft lb of torque. Bringing it to 329 rwhp and 334 ft lb of torque. Thats very close if not right at 400 hp at the flywheel accounting for the hp loss through the 80e trans.
No longer running lean. Cool part is that this is exactly where I guestimated it to be.
Now I just need to hold back this itch for a larger cam and focus on my turbo LSx 92 Camaro build. I do think that this truck could greatly benefit from a stall on this 80e though. I just have to remember that the purpose of this build is to be a street work truck to tow my Camaro around and not a race truck.

How To Adjust Holley Carburetor Vacuum Secondary Springs

The video describes the various rate secondary springs, how to change them, and the testing procedures to follow to make sure the secondaries open properly for best performance.
Hesitation Issue - need bigger pump cam?
I have a 350 engine, with a comp cam thumpr cam in it, which has lowered my vacuum, I put in a smaller power valve to keep it idleing, it stays running now at a solid 800-900rpms, but now I am having some terrible hesitation issues off idle, I'm guessing accelerator pump cam, or maybe the pump nozzle? I am currently running the stock cam that came with the carb, and the stock 35 nozzle.
The carb is a holley 670cfm aluminum street avenger, the distributor is an msd pro billet.
