You 230/236 guys need to step it up. I made my 12.32 @ 114 pass with 3.42gears and 245 Nittos. I don't see how I am so close with a smaller cam.

 

I'm not done...There will be an 11.xx pass from the car!

 

Chucklet,

Well done my good sir. Very well done.

 

Buzz12586, I'm going to venture an honest guess at answering this. Since we're talking about 6 speed cars here, what was your short time on that 12.32 pass? I ran my 12.210 on a 1.88 60' time. I'm just guessing(?) that the 114 vs 115.4 mph trap speed differences are the clue here.

 

1.88 60ft on my 12.32 pass.

 

1.601 60' on my 12.15 run, on the 10 bolt & stock suspension with a 230/236 cam

Did you spin at all on that 12.2 run? With more gear, suspension work and a 6 speed I would think it'd be quicker than 1.7's with no wheel spin. I know at MIR I was cutting 1.71's with my stock LT1 with just a converter and 3.73's.

Have you tried running at MIR yet? I don't know how good or bad Capital Raceway is, but if you cut 1.7's there with your mods, I'd be willing to bet you could get your 11 second pass at MIR no problem, along with your 1.6 60'

 

Buzz, this really makes the comparison easy then.

With your cam you ran the "back" (i.e. 1320' - 60' = 1260'), 1260 feet of the 1/4 mile in 10.44 (i.e. 12.32 - 1.88), seconds, and accelerated to 114 mph in the process; while I went 10.33 in the last 1260 feet and topped out at 115.42 mph.

This sounds pretty much right "on target" considering the cam duration differences. Remember the added lift we're running really doesn't help us with the stock heads, considering they really don't flow much more at .550" lift vs .500" lift. As you mentioned earlier, the performance difference between these two cams really does require running ported and/or better flowing heads.

 

Thats all I was saying. Why go with a bigger cam if you are going to stick with stock heads? I plan on going bigger ones I go to ported heads.

 

The cam isnt really that much bigger than yours 6 degrees all the way around with the same lift. That not huge to me, I bought this cam while looking for a 503 but got a good deal.

 

are you saying there's not a huge difference between a 230/236 and a 236/242?

 

i hope to have some times soon after i get mine back up and runnin....im thinking bout changin some stuff now tho.....NSA roller rockers n guide plates, bigger stall, bigger throttle body, suspension

 

What's wrong with having room to grow? The extra lift/duration doesn't hurt you unless your launching at 1500rpms
