Sorry. But its still damn fast for a 376!! I commend your build. I wish the AFR 245 cathedrals were out back then. I knew the 225s were leaving something on the table, but there was nothing I could do, so....

Thank you! It has exceeded my expectations and I have but 4 passes on it.
Came from the big block world when 300cfm was good for an oval port setup. Square port heads required gears, loose converter, solid roller, which took the car pretty much off the street.
So just made sense to me that the little 205's at 300 cfm would work quite well at 376 CID.
I had them, had the intake, and figured the cam would be at least ok.
Second consideration was budget. I'm in the short block for $1700.

I chuckled at the fact that you ran it on street rubber. Surprised you didn't hit both guardrails.......Ha!

Tq port lives matter!

My heads are like 255cc on a 5.7.....ancient ports. Probably won't move the car.

You guys and your low down torque.
None of you seem to have enough.
The switch is on.

I love this build. Ron those are some excellent track numbers from such a simple build. I'd feel comfortable betting that it feels like there are no compromises when driving it. No soggy down low too big of heads, no horrible idle and bucking from a huge cam, and no horrible driving from a huge stall. I bet it's like stock, just a hell of a lot faster.

Your parts list absolutely works together well and that's what the best builds do.

But... what intake is on this? I didn't see that listed... i'm gonna **** if you come back and say it's a OE cathedral intake.

My money's on an LS1...... LOL

At this point I wouldn't be surprised. He already blew half the people with giant heads and cams away, might as well have a 10 second car with a 4L60, 3.42's and a LS1 intake.

Just add this to the list of reasons I need a corvette.

Thanks. Intake is a Fast 102 with a 90mm restrictor and 90mm LS2 TB.
This all came from the LS1.
Bought the whole setup back in 2012 for $800. Rails and LS2 injectors included. I port matched it to the heads etc.

It drives identical to the the old LS1. Until I push the pedal down. 😊

Hey guys, was just an interesting experiment based on a smidge of experience, and of course in what I had keeping a budget.

Stuff to think about and of course it’s been a weird year.

Appreciate the comments!

I race stuff cause that’s what I do.

You all take care, I’ll resume in the spring. Season is over here in the PNW.

Those 225 AFR heads are why it had no traction!! My current setup has the LS7 heads. They picked up 40 horses at peak. But it was a huge mistake,, in my book. Because I spent all my time on Gen III internal engine, and C5 Forums, I never heard about the LS7 valve drop issues. I had just sent my AFR 225s to AFR for new guides. I bought new springs, their 8019s, and installed them myself. Then I bit on the LS7 heads. BIG mistake. Yes, the car is quicker, because of less torque under the curve, with a lot less tire burning. But it just doesn't feel as responsive, and I gave up about 3 mpg while on the freeway. The AFR exhaust port is far superior to the LS7 exhaust. The real kicker; I had to pay for the LS7 heads twice. First the purchase, then the guides were shot in 20,000 miles, along with several Ti intake valves. So, I now have about $4,000.00 in LS7 heads. Yes, I had that much in the 225 AFRs, when they were bought, and re-done. Like I said earlier, I got these 225s very early in their production run, by Christmas, 2004. 245 Cathedrals were WAY in the future. Now that they're out, if I had to do it again, I'd go with the AFR 245s. If I would install some Mickey T drag radials, and I'd have a mid to low 10 second car. I'm getting old, and with $8,000.00 in 2 sets of heads in the last 15 years, I'm married, and wanna stay that way!!!🤣🤣🤣😂😂

This is the reason why I went l for AFR 245cc heads over an ls7 setup.
The responsiveness and torque is very important for me especially in a heavy car.
An aftermarket LS7 style head should feel better with power under the curve etc.

I did almost hit a deer once at the strip!!! I was over 100mph and a deer comes bounding across my lane!!! Strip is in Ubly, Michigan, in the "Thumb". Very rural. Scary. One reason I never went with stickier tires was fear of blowing the rear end. 15 years ago their wasn't near the accrued knowledge on these cars as there is now. People running Goodrich drag radials were blowing out their rear ends. We found the BFG tires had really stiff sidewalls, at least at that time. Yeah, you gotta be making a lot of midrange torque to start spinning 2 315 wide PS2s at 60mph!! They aren't DRs, but they're pretty sticky for street tires, only a 200 tread wear rating......
