- This a video of me swapping out Pontiac 6x heads for some KRE (Kauffman Racing Equipment) aluminum cylinder heads along with the stock camshaft (189@50) out for a lunati camshaft 230@50 110lsa. Doing this gained me a lot power, thanks for watching.
I’m so happy to see kids doing this today! In 1987 I had a 72 formula that me and my buddy put a 455 out of a station wagon into-the most fun I ever had!!
Oh I bet! 455s are great before this 400 I had a 455 in it. Thanks for watching!
Definitely some stump pulling Pontiac POWER 🔥 Hunter always seemed easily scared. Glad you took it easy on her.
@@BigfootsnMopars ya I had too lol, thanks for watching mark!
That pulls real good. Especially if it’s a freeway gear under it. If you don’t have frame connectors under it, you need them. Now. Have fun!
PS the perfect carb for that is the Holley Street HP 750. It will be within 1/8th turn (idle air) of perfect out of the box. And give it all
the idle timing it will take.
You’ll see. It will get flat nasty, right out of the hole! 😁
@@apachebill right on!! I’ve got a Holley 750 with the choke tower cut off it just needs some trash cleaned out. Thanks for watching and commenting!
Great to see ya again! car sounds sweet man, had fun riding with ya on this one!
Great to hear! Thanks for watching skip
Sounds good and I like how you painted everything so it looks stock.
Thank you! I like it too, thanks for watching Nathan!
Good to see ya back on the poncho!
@@rockymeyers4030 yes sir!! Thanks for watching
I’ve been down that same road in Mexico-love Mexico roads!!
Gotta love it when someone plants a tree at a bend in the road 7:42
Ya that’s pretty dangerous spot
That thing sounds badass! Looks like it accelerates good too!
@@DanEBoyd thank you Dan! It moves pretty dang good. It moves even better without the little restrictive air filter element.
@@dakotastimeout2827 Man I was reading the news back home, and seen one of my old neighbors died. Lotta guys in my plat worked for GM, and he did too. They were a Pontiac family. Wife drove a dark green '70 Catalina two door hardtop, and his car was a Verdoro Green '67 or '68 Firebird with a black vinyl top and Rally IIs.
body on that car seems pretty solid dakota....400s always perform good. glad to see you enjoying it.
@@oldschooltwist18 pretty good for a 1974 model. I don’t think many 74s survived. Thanks for watching!
That V6 sounds nice.
Love it!
@@TheGto389 thanks for watching
Nice !!
@@colbranmx thanks for watching!
Good sounding engine!
@@kimfixesthings thank you
I like it. I like it a lot.
Glad I discovered your channel dude. I'm a mopar guy through and through but I bought a 1980 trans am when I was 14 and sold It to buy a 79 z28 which I then sold to buy a 71 340 roadrunner. How much hp is it making now with the heads? maybe more with a dyno tune?
@@davedaniels-q1h I think on an engine dyno it would make 400-450hp. I really like mopars too. I’m wanting to buy a 68-70 charger hopefully this year
@@dakotastimeout2827 Sounds real stout. I love those chargers too but I'm simply priced out of that market. Looking at buying a 68-72 satellite I can have fun with. Either a 383 or a 360.
@@dakotastimeout2827 I am around your age as well. It's nice to see some gen z taking care of these beautiful machines.
@@davedaniels-q1h I dont want to see too many people my age like these cars because I want to own as many as I can when all these old folks pass away.
What heads came off of the engine? #13's or #12's maybe?
@@memorylane7068 no the original heads were 6x-8s which are great in a 455 but on this this 400 it was about 7.5:1 compression ratio
@@dakotastimeout2827 Roger that.
More specs( gear ratios, exhaust, intake, cooling...)
@@curtpozzi5527 3.73 gears. Performer rpm intake, old Hedman 1.75” primary tube full length headers. Summit racing 2.5 exhaust kit with summit turbo mufflers. Nothing fancy in the bottom end the pistons are them 8 eye brow pistons that everyone talks bad about with the heads being rated for 74cc it would be around 9-9.5:1 compression ratio. Older lunati fly tapper cam 230/230 @50 292 advertised 110lsa. I’ve got the cheapest aluminum water pump on it I could find it was like 65$ on summit racing and the radiator is the factory one to my car best I can tell, and the radiator hoses are old ones that came with a car I bought I think lol
Cool ride but wash those windows!
@@2camsam the leaking heater core was making it fog up. It’s fixed now
be better and more streetable for daily driving with a properly tuned Qjet
@@taztaz728 I do not disagree, I’ve got a couple quadrajets that would be good to build but I think you would have to do some modifications for a 450hp engine.
Been thinking if changing to these heads on my 428 for my 65 GTO would be worth the money. Looks like it pulls pretty hard. What gear is in the TA? I'm guessing 3.08 or 3.23?
@@whodatnunyabiz6050 my TA has 3.73s. I bought my heads off of eBay and they was redone and ready to bolt on for about 1500$ taxes and all. Buying them brand new is over 3000$. I had to buy different length pushrods that were 200$ the head gaskets are about 100$ you’ve also got to buy different head bolts which will set you back another 100$. If I had to pay full price for the heads I wouldn’t have done it just because it’s so much money. I think home ported iron heads would do you good and save you a ton of money if you fount a set that didn’t need any machine work. Like 62 or 13 heads something like that.
@@dakotastimeout2827 Completely agree. I have the original #15 heads from the 69 428 that have the same port flow but smaller valves. Was going to port them out and put the 2.11 1.77 valves in it. I used to run a 1970 455 .060 (468) with #12 heads and flat tops (trw) that were opened up in the chambers. I ported them out and raised the roof on the exhaust side and blended the bowls with an intake port match to gasket and modified Torker that had the heat crossovers cut out. I ran a Crower Solid lifter .533 .555 lift (with 1.5s - I ran 1.65 Harland Sharp RR) 304 312 dur adv 252 260 @.050 lift. This was all in a 1970 TA with T400 (11" converter) and orig 12 bolt with 4.10s. Car ran 11.60s but was an animal on the street. On a 400 that gear is probably as good as you need.
@@whodatnunyabiz6050 that’s very impressive!!
@@dakotastimeout2827 also that was a killer deal on those heads! I would definitely run them if I only paid $1500 for them! SCORE!
@@whodatnunyabiz6050 ya I couldn’t pass them up, they was only on there for a little while before I bought them. They had the option to bid or to buy it now and I had seen the bid exceed the buy it now price too often so I went ahead and pulled the trigger. They was only like 1300$ before taxes.
Fresh heads on a wore out engine is going to show you just how gone your rings are in the form of major oil consumption.
The engine has been rebuilt. It does not have any major oil consumption problems
