What can I expect with this motor?

That is the just of it. What kind of power adders could I add in the future?

[GMC406]

O ya, it will have headers and timing is to be set at 34 degress advace at 2800rpm, vacum advance disconected.

[djracer]

That should run well. What do you plan to do with the truck?

[GMC406]

It will just be a fun pleasure driver for now, in the process of fixing it up, may make it to a drag at the occasional local car show, other than that just wanted a good fast street truck. Something to blow the doors off all the hot headed little boys with their parents vehicles in this little town I love my truck and just want it to perform. Hoping to get a base idea of what I can ecpect out of her, and if I could get a way with a turbo or supercharger down the road? I have never been a fan of NOS but how well would this work for me? Figured this would be a good forum to post in there is an amazing amount of knowledge floating around this site!

[djracer]

it should be pretty stout without a power adder.

I might would do a nice roller cam instead of a power adder. If you run the cam thats in it use a diesel oil since most oil is crap these days.

[GMC406]

I hear ya on the oil, it will never see anthing than Rotella T. All my vehicles without a catylitic converter run Rotella. Cant beat that stuff, in my opinion. It is also what the builder broke it in with as he is a firm beliver in in too. I am looking forward to see how much in woke up the truck, it always had a moderate 350 in it and it was fairly quick and a blast to drive with that, should be looking at 100-150hp past what I had. Now to find a tranny that will hold it... I bought a used stocker for cheap for now. The closest performance tranny shop from here wants 1200 to build me a tottaly built 350 Just will be a long time till I have the extra dough. Any you boys gotta decent 350 trans to get rid of cheap?

[djracer]

I have a couple of friends with 350's for sale if you are up for a road trip or some truck freight.

[GMC406]

Stout enough trannys to hold? And how much would one run including shipping to ks?

[djracer]

One of them has a manual valve body. It came out of a Malibu with a small block and a bunch of spray.

Send me a zip code if you want a quote.

[GMC406]

PMed you my zip, if you didnt get it it is 67642. Any guesses on what I could get out of truck in a 1/4? I was guessing 12s but a couple people around here have told me with this motor I should see mid 10s. I see mid 10s is all you run on motor and if im not mistaken you have alot more HP than I do, so I dont see 10s out of my truck right?

[Wild83C10]

12s with good traction and some good gears. But don't be surprised if you run low-mid 13s.

Nitrous is a power adder just like a turbo or supercharger. It adds more air to the combustion chamber. I was against Nitrous until I looked into it a bit more.

[GMC406]

Thats more like what I was thinking, for now it only has some 235-75 mudders so traction will be a big issue. It will get the 295-50s off my other truck soon, that will help but probably still wont hook solid. But it will rarely see a drag, mainly just for fun. Thanks for your input.

295-50 radials? Don't even bother. If the truck is a part time driver buy some drag radials. I had some 295-50 BFG radial T/A with my 375 hp 350 and those wouldn't hook at all.

[bigsnookmaster]

I ran Dunlop 275/60-15 radials on my short step wirh a 400 and went 13.12 at 103 on motor and 12.45 at 113 on a 150 shot.1.76 60 foot. It was fun on the street,pump gas ,and just the way I drove everyday.The motor was similar to what you have but I had World Products SportsmanII heads.I didn't like the ported 882's I had on it before the Sportsmans.Good Luck

[GMC406]

Ya Wild I may have to buy a set of drag radials to throw on the back whenever I need them. I will only get to run an 1/8 possibly a 1/4 like a couple times a year, whenever the local car shows come up. So I figured street tires would be my best option for the time being.
And bigsnook, what didnt you like about your old heads? And are you running a dry shot or wet shot, a lil drop of NOS is something I may be interested in in the future so any advice is greatly apriciated.
