CC'd Two Different 350 Heads

I would like to see a good 180 I was getting 185+ on my last test.

 

Yes I’d be interested also.
My 413 cam I had in my 350 I had 185 lbs cranking compression, I was actually surprised it was that much, but it did run strong tho

 

Was that with or without nitrous

 

Without nitrous and that 3500 convertor that could footbrake to 3000 the 60ft would be 1.80 350 trans, this is before the 2004r trans
With the 125 shot of nitrous 1.60 ft
75 shot with my 2004r trans and a 3000 stall 1.75
With the 2004r trans and the 3000 stall on the motor is 1.90 60 ft

I went to track a lot and as you see the bigger stall or more nitro better 60 fts
I ran the best times with the 3500 stall that I could footbrake to 3000

On my compression test if the engine went to the 5th revolution I would get 190 on the tester and 200 on the 6th revolution
After 5 revolution I do not know if they count but if I kept going till the tester stopped at about 7-8 revolutions it would hit 220 again I do not think it counts after 5 pumps/revolutions.

 

the fun before we go to work lol

 

Actually after the first pump, it should show strong pressure with one up stroke ( on compression) as thats the only chance the engine has to make pressure when running, so the first number is more telling.

 

True story right there…..

 

Once in the powerband the 284 is pretty impressive. Your 4 speed will be fun I'm sure. I have a 256 rear gear and stock converter. I can't do a break stand but if I'm in first gear going around a corner I can get the tires spinning and continue to roast them through 2nd. But there are other things about the cam I don't like though. I've never been able to get it to run good with the idle leaned out. It likes a rich idle. That might have something to do with the sp3 though. I think the cam will be fun with your combo but i do think alot of tuning is required to get it where you like it.

 

Maybe I'll do this sometime.

 

So the first pump is the most important? I never heard of that where does that information come from. So the first pump is more important than the 4th to fifth pump??

I know 4 pumps should be it and is done at that point, but I can't believe the first pump is the telling motion. It should be 1/4 of the total. I don't know, I never paid that much attention to that number. lol
I guess I will have to pay attention to that one

 

Its the most telling of the pressure the cylinder attains on the compression stroke when the engine is running, reason being the piston has just the one stroke (compression) to make pressure
