Streetable at highway speeds? I'm going to purchase a head/cam package within the next month and will be the first to admit I'm no expert. This is not a daily driver, only has 21k on it with stock gears, but it's in mint condition and I definitely want to keep the reliability of what I have now (being able to drive it on small trips if desired). My question is, on the more aggressive cams, are they streetable at say 1500-2k rpms while cruising on the highway or at that low rpm do you get the "surging"? I have searched and mostly see where people talk about the problems being at takeoff and with the autos. I prefer to go with one of the packages from Texas Speed, Futral or Thunder as they are probably the closest to me. This is not a track car but I do want a VERY aggressive lope and good usable power throughout. I don't care about revving to 10,000,000 rpm's and would rather not get into flycutting, etc. I want a great streetable package with mid 400's rwhp on motor only. Where do you draw the line in the specs? thanks...
Call Chuck @ HPE.
I am running his Mega Death Cam 244/242 6.12/6.10 112lsa. It has a really nice lope to it but not too extreme. I am still on stock heads for the time being and have not needed to flycut. Driving in 6th gear at 1800 with cruise you have no surging. The only time I feel surging is in a parking lot and the all I do is ride the clutch a little more. My peak power in the cam hits at 6400rpm so not rediculously high. He has many other setups just give him a call.

The surging comes at low mph....not highway speeds. Most of the time you can tune to fix it even at low speeds.
Secondly, if it not going to be a track car...then I would not recommend a cam that you have to rev to 6800rpm of more. You will probably not see that all that often on the street. Instead I would find something that had great low end and midrange that you can enjoy on the street as well as highway.

I really liked my dart head f14 combo I had. the came worked great and I would put at at the end of streetable for futral stuff. I know have more cubes and a bigger futral cam, and think f14 346 was a lot more streetable especially on the low side under 2k rpms.

i agree with sig
the futral F14 or the torquer V2 would make for great cams.
i'm running the torquer V1 and i can cruise at 1400-1800rpms in 6th on the highway no problem.
last trip i took, with alot of traffic on the highway (speeding up and slowing down) cuising at 80mph....got just under 24mpg....with a crappy part throttle tune.

whats wrong with just going with a set of ported LS6 heads and a 224 cam with a 112 LSA? That combo has been historically proven to put cars in the mid 400's while making it daily drivable as well.
Take a look at the Patrick G cam. It has gobs of torque for the street and more than enough for the track. It is a fantastic cam in terms of specs and "the science" that went into the creation of it. It is very well thought out and tested and has proven great results over and over again.

Not even remotely close to the "norm" with that combo. Nowhere has it been proven that LS6 heads with a TR244 will produce 450hp......if we are talking about rwhp.

Here's my suggestion. Afr 205's milled to 59 cc's, (go ahead and flycutt your pistons) and the g5x3 or g5x3 version II cam. The X3 vII cam with listed heads and all boltons made 490 rwhp, 445 rwtq. BTW over 20000 miles logged since my pistons were flycutt and no issues. As far as little trips, you have no worries bro. I have driven to Texas twice, and from Texas to Michigan 3 times. Thats 1200 miles (one way) and no issues to speak of at all. Awesome gas mileage too. Low 30's mpg (actual, not readout) I should mention though, the gas mileage wasn't that good until the ASP u/d pully and Meziere EWP were added. Those gave me a 4-5 mpg increase in gas mileage. No BS.
