I am building a budget 408 shortblock and was going to take all the stuff off my ls1, patriot 243's, Torquer 2, ls6 intake, about 11:1 compression. Is that cam too small for my application? Is anyone running anything similar? I have a Thunder Racing Custom Camshaft
"sTRoker" - 248/254 - .615/.623 - 112 lsa that i could put in there but i want some street manners about it. Also what size injectors do I need. It will be sprayed up to 150 a lot. Any info would be greatly appreciated.

there is a lot of duration on that "stroker" cam. i would do the v3 or something similar if you are worried about the street manners. i would say 42lb injectors with a fuel pump upgrade if not running a dedicated fuel system for the nitrous. if you are, 36lbs.

imo if your tuner is competent, the streetablility of that cam shouldnt be a problem

Strokers gain a lot of low end power over a stock stroke motor. With a decent tuner big cams can be very driveable in something like a 408.

i definetly want the low end aspect and my tuner is no doubt the best around this area. I am looking for about 450rwhp with this setup. Is that possible with the torquer cam or should i just throw in the stroker cam. It is used and came in my car with the ls1 and i had to change it so i don't know how old it is or anything like that. That is kinda why i am hesitant. Thanks for the input.

I would sell both of those cams and comprimise and run something in the middle like an MS4 It should have very good manners on those cubes with good torque and carry up top also....

That 248/254 cam was in your LS1??!! Did it have relieved pistons?

it was with stock heads at the time and a -4cc mahle piston. i really don't know anything about p to v clearance and all that jazz.

Atleast it had some sort of relief. I was thinking that you were looking at a new shortblock cause you got tired of floating and bending valves. hahahaha

Seems crazy to do that though. Wasnt a solid roller at one point was it? I know that sTRoker cam is a hydraulic cam, but...wow.

I'd agree that somewhere bwteen the two cams listed would suit you better!

With the 248/254 cam will be eatin up by the cubes of the bigger motor unlike having it in the smaller cube engine that makes it radical and a pain to drive around town if it were my car id go with the 248/254 try it what do u have to loose its paid for if u don't like it its not that hard to buy and change a cam.

If you have a good exhaust and the supporting bolt on mods, the Torquer 2 cam will get you to the 450rwhp mark, if that's all you really care about in terms of power. I'm not a big cam guy, but if it were me and you already have the "stroker" cam, a good dyno tune will still be streetable. You have enough compression, and the 112LSA will be very "tuneable".

Patrick G ran a cam with 239/241 duration on 112LSA and XER lobes on a 347 with great street manners...

It's all about the goals. I think the V2 would be pretty docile in a 408 and make nice power. I'd be very interested to see what kind of numbers it would make. I have a PatG cam in mine (235/243, .621/.623) which is not all that big for a 408. With bone stock 243 heads, an LS6 intake, and ported stock TB, I was able to make 448 rwhp. Mine drives great. Lots of power down low. I saw 400 rwtq from 3K on up. Great street car.

On the same dyno, a friend with a WS6 with stock bottom end, stock 243s and the V2 cam made 430 rwhp.
