1969 Chevelle with Spin Tech mufflers and custom exhaust
1969 Chevelle with the new Spin Tech Exhaust on it. Just a walk around clip of the
car idling for now. Sounds crazy when compared with the old Flowmaster 50
series muffs that used to be on the car :)

1976 Corvette Stingray Comp Cams Thumpr - Spintech mufflers - Edelbrock E-Street heads
Here is part 3 of the restoration and now modification of the engine on my
Corvette Project. A walkaround with idle rpm at 1000 in park and around
600-650 in gear. Vacuum is 7 hg and the base timing is 25 degrees with the
vacuum advance capped off and mechanical running around 20 degrees for a
total of 44.5 on my timing light.
At 2:45 sec in the video I was trying to show the vacuum canister mounted
on the frame under the brake Booster. If you end up getting a thumpr cam
and have power brakes make sure you get a canister, with the can the brakes
work the same as with the stock 17 hg of vacuum I used to have.
The new additions are:
Edelbrock E-TEC 64cc aluminum heads (#5089)
Comp Cams - Thumpr cam and lifters (#12-600-4CL)
Comp Cams High energy pushrods
Roller Tip rockers (Summit racing)
Double roller timing Chain
Milodon high volume water pump
Milodon high volume thermostat (160 degree)
Prostreet Harmonic Balancer
Edelbrock high volume fuel pump
Maradyne Electric fan and thermostat control.
Mufflers are Spintech Sportsman Street
Comp Cam Vacuum Canister (#5200)
IGGEE.com Synthetic Leather Seat covers (A++)
Transmission is a TH350 with stock convertor and a B/M shift kit set for
The rear gear is 3:08
It can really use a 2400-2600 stall converter and 3:55 to 3:70 gears.
All in all it's a good sounding cruiser with nice highway acceleration
though light hopping I haven't had a chance to try but without a convertor
there isn't much of a holeshot.
Thanks for watching and if you see anything else that I have listed feel
free to ask.
Flowmaster Muffler Comparison
A raw test of 7 different Flowmaster mufflers on one motor.
The Motor -
Small Block Chevy 406, 11:1 compression, Crane Solid Roller Camshaft,
Brodix heads with 2.05- 1.60 titanium valves, Eagle 4340 Crank, Eagle H
beam Rods, Manley Forged pistons, Victor Jr Intake manifold, 850 Holley DP,
K&N air filter, Moroso 7 qt. pan, 1 7/8 headers, BE COOL radiator with dual
13 inch fans, MSD distributor, MSD coil and MSD 6AL box.
Exhaust - Flowmaster 3 inch Scavenger
1976 C3 Thumpr Corvette Stingray - Spintech Sportsman 3000 XL Plus mufflers - Comp Thumpr Cam
Part 4 some part swaps. New Spintech mufflers and a big Thanks to Ron at
spintech for recommending them and getting them built so quickly. Great
tone with enough reduction in volume to make the car more enjoyable around
town. I also took the 600 double pumper off and installed a Holley 80770
Street Avenger 770cfm carb and what a difference that made, now the car
responds really well. I also installed an aluminum radiator since the car
was trying to run at 200 degrees with our cooler weather I knew summer
would be brutal. The new radiator has cooled things down by a good 20
degrees. I picked up a Mallory Hyfire IV ignition box and increased the jet
size in the primary and secondary and the car just keeps getting better.
