Okay I am wondering. Does a 5.3 head flow better then the head I already have on my car its a 98 Z-28. I plan on gettting a set of heads that came off a truck that is ported and wanted to know would it be worth the swap. Also what will be a good cam I want to spray 100- 150 shot wet. Ima thinking I can go ten's easy with all the bolton's and the head & cam swap.
10's is not easy by any means
5.3 heads when ported and milled flow good and bump compression. I think heads and cam and spray will get you there. Just have to have correct suspension, tires and size, a 12 bolt or 9 inch with proper gears and the list goes on. For
A real 10
Second car
this is true if you dont have the suspesion you will never get there
do you plan on running high octane unleaded with the nos ?you don't want to much compression only running pump gas when spraying.
Yea I am going to run race gas when on the spray @ least 110 or 112.
for one 112 lsa cams have been know fore the best power.... and u can run 12-1 on 93 with a good tune... but not if ur going to spray at the same time....
:lol: Where did you pull that from? :blah:Quote:

What would be a good cam for my stock motor with stock heads. I want to run on motor for awhile.
Have you guys seen some good dyno & 1/4 mile times with the 5.3 heads and a cam on nos and motor. What's the best you have seen with a bolt-on car with just cam and cam & nos stock heads and bottem end.
how much will you be paying for these 5.3 heads?
Don't no yet how much are a set of ported 5.3 heads worth?
ive seen them on ebay before for around $600. I have some that are still bolted to the block, that are not ported. They are numbered 799. If i dont use them, im gonna sell them
Bills98TA on here ran 10.81 with a 1.4 60' this past weekend and he is still working on his tune......24x/ 25x cam 5.3 heads 14:1 commpression and a 150 shot through an a4, 4:10 moser 9" rear and drag radials.......but he has all the suspension goodies and uses his wheelie bar when he launchesQuote:

I just can remeber the exact size the cam is, its huge for a stock cube ls1. 259/252 .607 lift 112 lsa (i just went back and checked on the size)Quote:

O OK hey Mark do you know any guys who run in the 10's on motor with head & cam? That can be driven daily.
Well that helps I knew it had to be on race fuel with that compression.Quote:

yup, I have a bunch or weight reduction, just put in solid motor mounts, poly bushings all around , new springs and a good set of 275/40/18's under the backend.... with my engine/ tranny mods if I hook good I should be thereQuote:

I kno I will need SFC. What are some good shocks to get. What other suspension?
SFC's, lower control arms, a set of Strano springs, and Koni's (or simular)........a good set of drag radials and you should hook like crazy.......id be looking at a 12 bolt or 9" to replace the weak stock 10 bolt rear when it goesQuote:

you can get standard height springs that won't drop it, but will perform betterQuote:

Don't forget the 5.3's need bigger valves too.
