Like always You have a plan that's good and You stick to it ! I would have gone to a set of good aftermarket head's that would probably be more cost effective than spending all the time and money reworking a set of stock head's . I like to save as much as I can . But what You are doing is build a period correct engine . Can't wait to see it completed and dynoed . Best Wishes and Thanks . 🇺🇲🇵🇷🦊👍
I know you from somewhere, aren't you that mustang guy that put a LS in your fox 🤔.......................😂🤣 Im messing with ya, you're like me anything sbf and you are there 😁👍🏼
Really enjoying your channel Brent. What seat and open spring pressures would you suggest for a 306, solid flat tappet, .549 lift road race usage build? Don't have the spec sheet in front of me, I think the Cam company recommended 135# seat 350# open
@@lykinsmotorsports Intake valve weight 114. grams Exhaust 92.5 grams, using ProMaxx cylinder heads. Cam .549 lift In and Ex. Duration .242 intake, .246 exhaust @.050. 108 Lobe separation. 1.6 shaft mount roller rockers. 5.4" rods, approx 9:8:1 compression. Forged rotating assembly zero balance internal. OEM 97' Explorer block. Arp fastners, Aluminum main cap girdle. mid 7000 rpm's based on gear ratios/tire size and the track I go to most often Mid-Ohio. Thanks for taking a look
@@jerrellkull5347 Only thing I can find is that they used to be a proprietary piston offered through Ross. Nothing current. Hard to beat a Diamond/CP/Racetec though.
Look at the pictures of the chambers again. A 1.940" valve would be .190" larger than what I have, which would be .095" larger on one side. That would put the valve right up against the chamber on one side and sticking up past the deck surface on another. Not that either one of those things is bad in and of itself, but sometimes you get more with less.....
@@lykinsmotorsports True, I forgot how small those chambers are. I use to have a set of C8OE 302 heads and they have those tinny chambers. I remember looking at them asking myself how I'm gonna replace these Briggs & Stratton valves with something bigger. Then I just gave them to a friend and didn't worry about it lol. Are you gonna dyno this 289? Not every day people get to see a 289 rip 💪
Catching up on old times.😊 Have a happy new year.
Hope u had a nice Christmas 🎄!

can't wait to see how much power this makes!

This build is awesome. It takes me back to highschool. I built an 84 Ranger with a 289. I hope it gets put on the dyno.
Can't wait for more 289 info. Also I speak for many when I say please build a Cleveland!
Ahh brings back memories! Live time engine builder here. Good job on the videos! I’ll hit you with a sub.
A little hi revving 289!!!💪💪💪
It won't be a high revver.
@@lykinsmotorsports right!!! I figured you would build it with better parts to get afew more rpm and hp out of it!!!
Great video
Can bigger valves be installed

I'd have to see the cam specs, know the valve weights, know how high you're going to turn it, etc.

Hey Brent, you ever used Nowak pistons? Definitely next level parts, and machine work.Take care.
Never heard of them......can't find them on the internet.

@@lykinsmotorsports hmm ok.
What do you think about the 302 Mexican block???
*Very* beefy.
They plan to turn a high RPM
Brent, Im surprised you are not gonna put 1.94 / 1.60 valves. in these heads.

1.75 intake and 1.5 exhaust? That's tiny...where they 1.67/1.45? I think years back the machine shop installed 1.90/1.60 in my 64 289?
Yes, 1.67/1.45 is factory size. It varies from head to head, but on these, I think a 1.900" would have been pretty shrouded.
How about a cross bolt main 406 with 3 duces ?
very few of those blocks around
It looks like the Port Walls and floor had Port work why do the valve seats before the ports
They have had zero work.
