1320 divided by 106.82 = 12.35
1320 divided by 104.87 = 12.58
1320 divided by 108.38 = 12.17
And this is only a jumping off point you can do much better
The DA does not matter here, talking about cylinder heads is one thing, in my opinion the main focus should be learning how to make the rolling car work, because you are not utilizing your HP, just advice.
I understand that. And thanks for the interesting breakdown.
Yes. This was about making HP with small heads however the topic veered off a little and I was demonstrating my affinity for the correction factors. Then I it turned it into my vehicles performance which at the start, I had deliberately avoided so as not cloud the issue as I've manged to do here.
I'll be the first to admit that this is not a drag car. It's just a car I take to the drag strip. Typically I'm mostly interested in the MPH as it reflects what I enjoy most about cars and that's engines and engine performance. It's ET however that catches most people's attention. I've an 11 second street car. The new Demon runs 9's. And so on.
That said, even with the older engine, not this current 355 with the ported heads and 288 but rather the out of the box RHS Vortec heads with a custom roller of 274 degrees version, it still made some steam. It has gone an uncorrected
107.65. And as you point out, "learning how to make the rolling car work" with a better converter, some gearing and decent traction it would be a low 12 second car (there's that ET reference again) and the jump to 11's would be a simple step involving a 385. Maybe even with the untested 355 that's going to be laid to rest (maybe).
Anyway, all of this is appreciated. And thanks again.
As far as the heads and 385, I've got some work to do before moving too far along with it. Mainly determining the cost effectiveness of reusing the old block and getting a reciprocating assembly or buying a complete shortblock altogether. It might even be that if the 355 isn't too wasted, perhaps a re-ring and re-bearing (and possibly a better spec cam) will be the order of the day.
Maybe that's a subject for another thread.
