i hate to say i am getting a little bored with my camaro (even though i am within months of building the 400SBC). 350 Holley 780 CFM. my compression numbers are all within 10%, i dont puff any blue or burn a noticable amount of oil, have any odd sounds or knock or anything. as far as miles on the engine and internals i have no idea (as i am just opting to build a 400 and shove the 350 into something else at a later point).

what is all of you thoughts on spray?

its not a daily driver, so reliability isnt a big deal (as long as it can get me back home from the track or a cruise).

i would spray conservatively, even if i were to mess the engine up, it wouldnt be a big deal, just she would be out of comission a little longer.

would you spray it, or not??? what would you think would be a safe shot?

 

If cast pistons, no more than a 100 shot.

 

thats around what i was thinking in terms of shot.

i am definitely thinking NOS (Nitrous Oxide Systems) i hate the word NOS... lol.

i have a lot of faith in Holley and their sub-brands.

thoughts on that?

 

I just put an Edelbrock Performer 50-75-100 kit on the '57. I had an issue with the bottle nut washer, other than that, it has worked very well.

 

im not a big edelbrock fan though. [IMO] i think they make too many products and honestly i dont think they have mastered much of any of their products.

 

Spray the mess out of it. work up to 150HP+. If you are not careless you won't hurt a thing and have a hell of a lot of fun doing it.

 

Just make sure you have plenty of fuel delivery capacity. That's the key to any boosting, nitrous or forced. You need extra fuel to prevent knock.

 

Exactly, lean is the enemy. If you have a wideband (a tool I encourage everybody to have), you can push the limits safely.

 

I would spray it. As long as you run nitrous lean, you shouldnt have a problem with a 100 shot on cast pistons. Been there, done that. As for a 150 shot on cast pistons, I dont think it will hurt it, as long as there is more fuel then nitrous. My favorite saying is... " Nitrous is like a ****, you want to hit it, but your afraid of the concequences"

 

as far as fuel delivery goes i am going to be getting either a holley blue or black. depends if i feel like running methanol in the future. but i am thinking most likely blue. i dont know the size off hand but it will be sufficent.

 

A wide band is nice, but a fuel pressure gauge that you can read while driving is a must. It will tell you that the mixture is fixing to go lean. The NO² will also help with the transition to the 400 by pointing out drivetrain weakness (like traction).
If you plan to eventually spray the 400 and haven't built it yet, be generous with the ring gap.
Remember, these cars are steel, plastic and some rubber. That's all they are. Have some fun with it. That's what they are for.

 

i am definitely going to be getting a wideband either with the spray or before i get the spray for tuning. the fuel delivery will be fine, i have talked to a few Holley techs today about adequate fuel delivery for spray.

traction shouldnt be much of an issue. lower control arms w/tie rod ends as well as panhead bar. 90/10's and 50/50's moroso 220 in. lb. one the front.

as far as trans... that might be interesting and possibly the rear as well.

 

Plentiful fuel is necessary, but not sufficient. You should also run higher octane, and back off the advance when spraying. I'm running an MSD Digital 6 which allows you to retard the timing when an input wire is powered - just tie it to the solenoid power or trigger.

 

i already run premium and i was going to back off the timing 4 or 5 degrees for a 100-125 shot.
