I'd pass if I were you. What's his number anyway?

Thanks for the pics mike i do not have a resizer on this computer for some reason....they way you see is the way i get it....the carb is brand new......the headers go too....he is going 98 350 vortec.....all computer

Wynne is right lol.

Eric, I would try and snatch it up, if you pass let us know. I like that old Weiand intake, Kevin has one like it for his motor.

What would you say the going price for that would be now that you hsve s eye on it...I cranked it up which i had to jump it off and it had been sitting for a week or better and no smoke....had good oil presure too....

Eric

Mike let me ask a stupid qusetion that i already probly know... Why do the spark plugs slant one direction on one side and slant the other direction on the other? Oh by the way there was no getting no numbers from the back of the motor....lol too dang tight!!!!

Eric,
I don't know what it's worth, has he set a price? It's probably worth a lot more than I told you because you are getting a lot for your money. It would probably cost a couple of grand or more to build it seeing how it's so complete. The plugs slant toward the exhaust valve, both heads are identical and swap side to side. Something to do with quench or something another I guess. 90% it's a 454, there aren't many 427's or 396's floating around anymore and 454's are pretty common. It sounds like he upgraded quite a bit. Stock lo po 454's from that era had 5/16" pushrods and you said he put the bigger ones in. 396's, 402's and 427's usually had 3/8" and higher perf versions had 7/16".It's pretty common to upgrade a low performance 454 with 3/8" pushrods because any kind of added spring pressure (or big cam) will fold those 5/16" pushrods up. Ask me how I know. Of course he could have added 7/16" pushrods as well but they are big bucks and they only came in real high perf big blocks. Gotta have the correct guide plates for the pushrods. I have 3/8" in mine. If it has flat tops it will be real low compresion, probably around 8 to 8.5:1 or so with a set of 049's or 781's. It will run on regular unleaded and be a good street motor. Try to find out if it has cast, forged or hypertutectic (sp?) pistons. This really raises the price depending on which ones it has. Too bad you can't pull a valve cover. The later model peanut ports are crap and run out of wind real quick. They do make great bottom end torque but wheeze out over about 3500 rpm.

Mike

Thanks for the info Mike....that really helps me out...I am not sure but i think he said they may be kieth black flat tops!!!!!!I do know they change the guide plates for the bigger push rods and the bigger springs.....

Eric

Oh one more thing will a turbo 350 hold up behind that....The turbo 400 is in there but it has leaks and just not sure about it i know i would like to go though it but he said it pulls good......

Eric

Thats headerman headers on there with the ball and cup ends.....the carb is brand new stiill has the box for it......lol

Keith Blacks are good but are they cast, forged or what? Price goes from cast-cheap, ,,,,Hypertutectic- a little more,,,,, forged- expensive but bulletproof.

I have TRW forged in mine, they are a copy of the old LS-6 pistons with a little .250" dome and I'm running 10.25:1.....yeah I need premium gas but it will haul a$$.

I'm betting they are hypertutectic since that is the big ones KB sells, they are real good for the money and should last. You can hammer on them and they will stay together. I have pulled more than one cast piston in half over the years running big blocks but I was not being kind to them.

Mike

A 350 will last OK if you treat it well but if you rawhide it that 454 will gut it. Having said that I had a friend that had a 396 in a Nova that ran high 11's on a good day but would knock down 12 flat anytime. He had a well built 350 in it and it lasted about 4 years. It was an exceptional feat but in a heavy truck I would take it easy. There's a lot of difference in a 454 versus a 396. That longer stroke makes a bunch more torque and it will kill that tranny if you are not careful. 400's are the way to go behind a big block. If the price is right it would be a good setup to buy.

Mike

Thanks buddy....Is the price to build a 400 about the same as a 350 turbo????
