DAMN! 408 dyno.

[CuNfUzEd]

Don't feel bad I got 380 hp 355 torque on a 408. It has 317 heads with a little work, headers, 224 cam, 20 inch tires, 4l60 trans, 4:10 gears, approx 10.5 compression. I should have went with a smaller tire on the dyno but oh well. I am like you the numbers on the dynojet are what they are. Just going to work on track times and not worry about it. Like one of the others said you don't run with a dyno under it. The way I see some people chase numbers on a dyno and some want numbers on the track. My tuner said he make the dyno show any number I want but that is not what matters.

Yeah that smarts!LOL I'd be a little down too. What is your weight and what times do you knock down?

I agree with Red.

I agree with Red.

Me too, i think you should have put a slightly larger cam in it, with a wide lsa, "to keep it mild".

Yeah probably.LOL The thing is, when the 5.3 went, I built this for 3500 bucks. So, that being said, I reused the stock stall. If I went any higher, I would of had to buy a stall. I am going to end up buying some L92's for it and see what that does. Anyone know where I can buy some cheap headers for this thing? Everything I am finding is higher than giraff pu$$y.

I'm a long time lurker on this site, but it looks as if your compression ratio is too low...as in like ~8:1. I may be wrong, but the dish from those pistons looks more like a boost-centered build.

[GasGuzzler]

I was wondering as well....

[GA95DCMSS]

Just making sure it wasn't me. This is what I came up with using the compression calculator:

[CuNfUzEd]

Are you positive? Man my computer formula tells me something COMPLETELY different. TSP calculated it for me too. Not saying your wrong, just want to be sure.LOL If that's the case, I am going to go by the biggest GD KB charger I can find.

[CuNfUzEd]

Yeah the formula I am using is 10.8.1
Engine Compression Ratio (CR) Calculator

Aren't stock 243's 65cc chamers? It's been so long sine I have used anything stock.

Bore 4
stroke 4
Gasket 4.03
thickness .040
chamber 65
dish -10
