Well Just got back from the track and am very excited.
I just swapped to solid roller 242/242 @ 112 lsa.
First pass out was 11.62 @ 119 twin to hyd cam best, Then I added 1 degree total adv. from 35 - 36 only above 4800 and added 5% to upper VE from 2500-5600.
That is what netted me a new best of 11.55 @ 120 MPH, also all times are all natural and using 93 pump gas only while still running through SLP shorty headers.
I think next week I am going to uncap the shorties and see what happens,I,m sure it will pick up my ET some more.

 

Sweet.

 

87_ta are you going to keystone next week on the 9-6-03 if so mabe ill see you there good luck

 

Hey Cork,
Yeah long as the weather is good I will be there.
Good luck to you as well.
I hear you are getting sub 1.5 60ft times, I look forward to seeing that.

 

yea lets hope for some good low humidity weather
keystone allways had a good hook so maybe i can improve that 1:48 60ft

 

Congrats on the new best. Gotta love how those Minirams pull on the top end. The one motor I built using one was a much milder 400 than yours and it went just a hair shy of 111 MPH in a big fat 87 GTA with auto trans weighing in at 3900 lbs with driver. Best I ever went with that same motor with a carburetor was 108 in a car that weighed about 250lbs less.

 

Thanks Damon,
Thats nice to hear about the carb, I keep contemplating throwing the 400 in my camaro with carb just to see.
But I still have more to get from this combo yet, then I may throw a 100 shot on it.

 

you went fron hydr. to solid cam? did you go solid roller? did you come from hyd. roller? did you change the valve springs? if so what springs did you use, and what lifters?

 

From Hyd Roller to Solid Roller, Yep changed springs.
The spring i'm using are a little excessive but they are all I could find without pulling heads to machine. 200lbs seat 484lbs peak lift .572, Comp Cams link bar lifters.
