    Real bad timing for us as far as financially, but Joleen will be getting herself a bruit under the hood prolly this weekend. Nick sweet talked his boss into putting the motor on his account. Edelbrock intake is ordered, as well as chrome valve covers. Everything else on the 350 that's in there is new or just about new. We'll paint it good ol chevy orange. The motor is rated at 375hp 475ft/lbs. Now I'll be able to give you a good opinion about that motor instead of hear say [​IMG].

    What's ya'll opinion on the best way to break in a motor? I've heard, 250 miles in the city, 250 miles on the highway...baby it for 500 miles......drive it like normal for 500 miles......keep it in the city for 500 miles.....keep it on the highway..etc..

    I've got a mind like a . . . a . . . what's that thing called?

    Sounds sweet! Keep us posted. What all do you have to change to go from a stock 350 to dropping in a crate 383? Thanks!

    You are about to experience a rush of power. Low end torque difference between a stock 350 and a built 383 is awsome! I break in every new engine the same for the first 500 miles. Don't idle them very long, don't lug 'em down too hard, don't rev them too high for too long and don't miss a gear. Other than that, change oil after the first 50 miles & then again at 500 miles. Vary the RPM's often and wipe the smile off your face, otherwise everyone will think you're on something.

    87 K5, D60 & 14FF, 5 sp & NP208 & 383 stroker. Build it Bulletproof and take it fishing!

    Congrats. You will love it. I put a 378 (Std bore stroker) in my Suburban. 350HP and 450 Ft Lbs did wonders for the Heavy Pig. Can't wait to get the gearing changed. I tried to put as many Highway miles on it as possible, but there are still a bunch of city miles. I just tried to keep varying the RPM's as much as possible. I changed the Oil after 100 Miles, and then again at 500.

    If at first you don't succeed, failure may be your style...

    Here is a link to the recommended startup & break-in procedure that is recommended for GM Performance crate engines. It should be good for any new engine.[​IMG]

    go to the link 502 burban put up i dont like the running it up to 5000rpm's but if thats what gm says then you can use your owen judgment but one thing they dont say is when at freeway speeds dont stay at 55 or 60 for very long as that is not a good thing to do. everyone is going to have diferent opinions about how to break in a new motor so just look at everyones advice and combine them all and do what you think is right HTH oh and congrats on the new motor

    I break the cam in, change the oil, and beat it as usual! I can't wait, got to feel that power.

    I think if I ever get the NV 4500 I crave so much I'm going with a 406.

    Ya, it's the Napa one. Our price is 1300 [​IMG]. I'm wondering if I should paint the brackets black or aluminum. I'll have chrome valve covers and the edelbrock intake. What cha think?

    I've got a mind like a . . . a . . . what's that thing called?

    <font color=purple> Oh yeah, break in period should be 500 miles ......fluctuate your r.p.m.s and don't idle for tooo long .......do a good cam break in if it's not already done on those ....change oil after about 50 miles and then again after the 500 mile point ........cut open your oil filter and give it a good once over.........then ENJOY !!!!!!!

    The usual answer to that would be to build it yourself.

    I would paint the inside a nice gloss black restoleum. Then you can either match the brackets to the orange, the gloss black, or try something different. I usually go the gloss black route cause I run all black oxide arp bolts and studs... love how they contrast w/ the chrome and brushed alum. I have seen some motors that have the brackets painted w/ the brushed alum color to match the intake manifold... then the pulleys were gloss black and the only chrome was the air cleaner and valve covers. Looked pretty slick. But I really wouldn't worry too much about it unless you have/are getting jet-hot coated headers... crudded headers tend to make even the best paineted engine look bad... plus wtf? You think you are gonna be sitt'n around w/ the hood popped? Hell no... You'll be busy driv'n. Plus w/ the lift and some tire they'll need some steps or a box to stand on anyways [​IMG] LOL.

    Even Jet-Hot coated headers start to look crappy when you get them muddy all the time.

    I'm not painting the headers. That'd be a waist of my time. I want it to look pretty for pics once...which means painting the motor and brackets.
    I've had a 383 in a dually that had 4.56 gears I think and with the 4 speed. It would out pull a big block any day. I had her hooked up to a buddies 454 one ton. He had a 4 spd also. My dually pulled his truck backwards while he was pulling. He quit dogging my small block after that.
    As for the price I get, Nick works at Napa so we get everything at cost. The motor I'm putting in retails a 2K. It's a fourstar motor. The cylinder walls aren't even bored, so you could have the block bored out if you wanted. My dually got pretty good milage for the power I was getting. Definatly better milage than a big block. I'll keep you posted. I'll have to give readings on gas milage after I put some miles on her so it will be a fair reading. I'm expecting horrid gas milage until she breaks in. [​IMG].
    I'm grinning just thinking about what a stroker motor will sound like thru those flowmasters. The motor has an above mild (for lack of a better word) cam so she'll lope some [​IMG]. I can't wait!

    I've got a mind like a . . . a . . . what's that thing called?
