I have 120k on mine, and thinking of either H/c or just a cam this winter. Just wanted to hear some input on it?Also best place for buying a 355 or 383 short block?The motor in my car is healthly as it can be it goes 12.40's Stock internal @108? Any input in a cam only setup would help too

one question how does your car run 12.4's @ 108 when mine runs 13 flat at the same mph with a 2.0 60ft does knockin off .4 on the 60ft add .6 in the 1/4? and without a cam

BTW i went with heads and cam package @92k on my 95

 

his 60'

 

so your saying if i drop my 60' .4's i should easily gain .5 in the 1/4 and have a slightly modded 12 sec LT1??

 

If you had a 2.0 60ft and you got it to 1.7 you would run 12.55,for every tenth on the starting line you pick up another .05 going down the track.

2.0-1.7= .30 +.15 =.45 off your ET

 

On average, ever tenth taken off the 60' gaines you 1.5-2 tenths on the big end. Transamtom beat me to it.

I had ~120k on mine when I did my cam swap. You should be fine. I gotta know youre race weight though.

 

interesting... Thats all i can say

 

Get some sticky tires,loosen or remove the front sway bar and use some softer shocks and a 13.0 with a 2.0 60ft will turn into a mid 12.

 

BTW I am doing my H/C swap this winter with 100,000miles(166,000km) this engine is still strong.

 

i dont know my race weight but its a hardtop z28 with prostars maybe in the 3400 to 3500 range im quessing

 

What are your mods if you dont mind me asking? Those are some nice times.

Something else if you arent sure about your motor, just run a compression test and if it checks out alright, then Id feel safe about modding it.
