Same as everyone else..... Cam selection

Just bought an LS1/4L60E combo from a '99 Firebird/Trans-am and planning to transplant it into my '87 S10 Blazer. As far as i have been told and by looking at the engine, everything is stock. I really don't have the $$ to do a complete rebuild but would like a little thump with some added power. Stock the engine has about 330 hp and was looking for around 400hp( I know just throwing a cam in it will not get it up that high without doing other mods). I have 411 POSI-TRAC gearing in the rear end and don't plan on changing it.

So the big question..... Which cam would be the best without having to swap lifters/springs and so on with a really nice power curve? Not looking to spin the engine up over 6000 rpm.

Without swapping the valve springs, the stock cam is as big as you can go.

OK, what would you recommend if it was your engine? Being budget wise of course. This is my first LS1 build.

Call Comp Cams or Texas Speed and talk to a tech. I'm looking for a cam myself and they gave me some good idea's.

^what he said. But also to put my .02 in, are you an manual or automatic, I forget what s10s came in. Also what do you consider budget friendly. If it were me I would get the vindicator cam which is 240/244 duration .596/.605 lift(I think) 112 LSA. This is the cam I am going to get when I have the funds. I would match it with a 4000 stall or ls7 clutch if you are a manual. Then get some comp cams dual springs that are rated to .650 lift and some hardened pushrods, c5-r timing chain, and a better oil pump. But, this is what I am going to do and that cam is pretty big so it may not work for you. But if you don't have an upgraded clutch or stall then the best you can really do is the 224 or possibly the 228r cam from texas speed. With either of those you need springs that are at a minimum good to .600 lift and I would upgrade your timing chain and oil pump while you are under there. Texas Speed sells complete cam kits that includes pretty much everything you would need for the swap. The best thing to do would be to contact Texas Speed, Vengeance Racing, Thunder Racing, or another place like that and tell them what your goals are and they will give you some suggestions.
