You didn't include that the engine mentioned was on E85. 12-1 on E 85 is about 15-1 on gas. That's super lean. A gas engine will be pig rich at 10-1 Doug

Happy Birthday Polywideblock! Hope you have a great one! :bday: :bday::bday::bday::bday::bday::bday::thumbsup:

On top of that the Dynomax's are stainless, unlike the Flowmaster's just being steel.

My parents made me take Latin in 7th and 8th grade. I hated it so much that they switched me to French in 9th grade. I hated that as well.

Why do many need a 3000hp capable trans in a less than 1000hp application? Especially with all the related mods to install it? Personally a GM 4L60 or a 200 4R would be an easier fit. Even a better trans? I'd be leaning to a ZF 8HP70. The amount of fuel cost savings will never be recouped with...

I'm a copper coat guy too. My dad used it for years so it works for me.

i hear you,,,,here's the thread page 1 half way down. Indy EZ/440-1, Victor, RPM Perf or Stealth Heads for 440????

But what about the first two on vin same thing I assume

The first two were stamped from the top down, with different stamps, so that is why they look different. The 80 under AB on your tag is 426 wedge.

There is no way that changing the actual F/A ratio from a real 12-1 to 10-1 would add power. Nor would it add 160 hp. Now maybe if it was misfiring at 14.8-15.0-1 down to 12.8-13.2 there could've been a big gain. When the last time anybody has seen a N/A engine make peak at 10-1?. Doug

The trunk wasn't closed completely when I took the Pic. It is perfectly aligned when closed. Car was originally Turquoise.

Happy birthday @polywideblock! :bday: :bday: :bday:

Are these the Flowmaster 50's? They sound great in the clip! Any drone or other downsides? Thx

Can someone send me pictures of where the front bucket seatbelts mount So I don't have to take out the seats & carpet to find them....THX

Ok I was thinking that's what probably was done.

In those years the VIN plates were pre stamped with the year, plant, and sequence number, and the first two characters were stamped later when the type of car was known.

here's an interesting thought on making peak HP i clipped ..IQ52 posted this .. "" it made 680 HP at 12:1 AFR, 760 HP AT 11:1 AFR and the 840 HP @ 10:1 AFR. I think with some more fuel it still had some horsepower in it."" at .700 lift its real close to the TF270 at 355...Gained 160 HP just by...

That was the casting number. He's asking about the VIN that is stamped down by the oil pan rail
