PONTIAC - stock Pontiac Super Duty 421v8/405hp vs stock Chevy 409v8/409hp on DYNO
WATCH THE VID TO SEE HOW CLOSE THEY Dyno TO THEIR FACTORY 405hp/409hp ratings. Growing up.....Pontiac/Oldsmobile old timers/EXPERTS who taught me most of what I know, often told me Chevy rated their horsepower in a more optimistic way than say Oldsmobile or Pontiac. I've even heard Pontiac rated/tested their engines in a 100 degree room, compared to Chevy in a 60 degree room. These Dyno results seem to reflect that some of what I heard was true. Both of these engines are great, but the results do seem to show that Pontiac was not rating their horsepower worrying if it would cause "songs to be written" about their engines .... like the great song "She's real fine my 409"--(Chevy).





Pump Gas Pontiac engine 468 cid by Tin Indian Performance 600 rpm dyno pull 558 hp 583 tq
This is a 468 cid Pontiac engine we build to Mike Matuszek and his '66 GTO. The engine is based off a 455 cid pontiac block. An Eagle crank and rod combo was used on the bottom end along with a set of KB forged pistons. A Tin Indian Performance custom ground Comp Cams hyd roller was also used with Comp Cams hyd roller lifters. The engine is topped off with Performer RPM cylinder heads and intake. We also used one of our custom 4150 1" spacers with the 950 cfm PRO Systems carb. The combo pulled 11" of vac at 850 rpm! It made 558 hp and 583 ft lbs of torque. ALL ON PUMP GAS!!! This is a 600 rpm per pull
