You can hit 11s with an LT4 Hotcam set up. Here is one example

Look at his mods though. 11.45:1 compression, trans brake etc. I would just upgrade to something a little bigger.

wow steve nice car any problems with that hotcam like on the street or tuning and home ported heads were did you learn and is it hard sorry for all the q's try to bulid this thing right
the hotcam acts just like a stock cam on the street only difference is a very slightly choppy idle, and more power, other than that its great...
porting my heads, well I just looked on the internet and saw what others had done and tried to copy, made the port taller and opened it to a felpro 1206 SBC intake gasket port, smoothed the inside wall for better transition, ground on the valve guide bosses and airfoil shaped them, and had a 3 angle race valve job done at houston engine and ballencing where I used to work, pics of the heads are on my cardomain site in signature

10 LS Engine Myths That Refuse to Die
Verdad Gallardo Unless you plan on a very mild port job (gasket match, bowl work) or are an expert TIG welder, I would HIGHLY not recommend it, the LT1 heads are incredibly thin and I ported through in two spots, luckily only by the pushrods, and my dad is an awsome tig welder so he welded the holes shut, and I ground the weld back, but if you port into the water jacket you're f*cked and it will take about 40 hours or more to Really port a set of heads Im just happy mine turned out so well it was about 70% skill 30% luck.
Sorry, i just read that you had a t-brake in the other thread. Anyways, your car runs amazingly well for what it has, and i would not be expecting that out of everyone running similar. To answer your question i would go with something bigger than a hot cam, maybe a 230/236 or something like that.

there is one guy in the valley(south texas) that will do it for me for about 400bucks and he leaves them like CNC.... but if i was careful could be done.... i would really like to do them my self one to learn and to brag about it when i beat people... and i think that i am going to go with the hot cam...steve is proof that it can be done and my car is going to see a lot of street and steve when are going to spray that thing do you see 10's coming up
actually I want to swap to a solid roller setup and hit 10.90s before I spray, swap out the valves to stock size stainless, and spray about a 150 shot to be what I beleive would be the first stock LT1 head casting car in the 9s

I run the Hot Cam in My Vette w/ Ported heads, small stall and boltons. I run high 12s running with the stock 2.59 rear end, stock tires, with traction control on cutting 2.0 second 60'. With just 3.55 gears and some slicks I am mid to low 12s easy at a horrible track (Atlanta Dragway). I see high 11s from the right setup at the right track easy.
Just curious so dont bash me but a buddy of mine up in Knoxville TN said all the LT1 guys there say the hot cam is a waste and that the CC 306 is the best or an Overton cam....Why so many hotcam haters do you think? Jus wonderin cuz i might get around to doing a cam only setup on my 95Z

Boltons lets see.. Hooker Long tubes, !AIR, !EGR, !Stock Air filter box, TB coolant bypass, K&N Filter, home ported MAF..... I think thats about it, the only one worth a damn is really the Headers, for exhaust I just bolted on some 3" Chinese no name mufflers that flow like a son of a gun and dont change the sound of the car at all, just quiets it, I love 'em.
