CHESTNUTXE 7,311 Posted January 1, 2020 If you are using the original cam then take the gear of the AU piece and put on another dizzy. Just make sure the shaft size is the same. The steel gears use to be about $40, that was 10 years ago for me. I used Mallory steel gear and a Mallory dizzy and the roll pin had to be re drilled to suit.

NZXD 2,328 Posted January 1, 2020 What’s the diameter of the shaft that goes into the hole for the oil pump drive? Sent from my iPhone using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

NZXD 2,328 Posted January 2, 2020 Might have to apply some heat to it. I’m sure we pressed the steel gear on to the dizzy for mine. Sent from my iPhone using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

Boingk 862 Posted January 3, 2020 Lookin' good matey! You going to see how she runs just like that? I'd be pretty tempted so long as the carby's up to scratch, or swap out for a 2bbl 500 if you have one handy. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
NZXD 2,328 Posted January 3, 2020 I’d be interested to see how that goes, it’s quite surprising how much carb these little things can take. When I was shopping around for a carb for mine the consensus was the usual 600cfm vac sec, but it never really ran right. Thinking it was too big went down to a quick fuel 450 dp and it was better in the idle to mid range and then went flat. Took a gamble on a new Quick fuel 650dp and basically straight out of the box it was mint. Tuned it using the wide band afr and it starts easy, revs crisp as hell and has steady afr right up to 6500.

gerg 10,871 Posted January 3, 2020 Your roller cam firing order is the same as a Clevo or "Mustang", ie: 13726548. The earlier one was phased out in the 80s (for some reason they kept it until then) but all other Ford smallblocks (351W/351C/400/4.6/5.4 Modular) use the later one. Beats the fuck out of me, but reasons I guess.That Motorcraft carby would be a better one to use than a 350. They are near bulletproof, and have annular boosters vs standard ones in the Holley. Probably rated at a similar CFM anyway. Sent from my CPH1903 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

The Summit brand carby is the latest rehash, still selling well for price and out-of-the-box running. I wouldn't baulk at using one. I had a 600 Vac 4010 and it was pretty good. Just that the aluminium body would act like a pot on a stove. Hot days were a shit. Sent from my CPH1903 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

Boingk 862 Posted January 3, 2020 Nice one mate, an original carb would be worth running on it even just for simplicity sake. I wouldn't use a 350 Holley as they are really only a 250cfm job by 4bbl rating standards, and the 500 is a 375cfm by that measure. Check for yourself and you'll see the 500 has the same venturi diameter as a 750cfm 4bbl. I've used 350's on Ford 250's and Chrysler 245's and they don't work too well there, needing substantial rejetting and tweaking. If you can get a 500 go for that, otherwise a 4bbl with an adaptor would be better than a Holley 350. - boingk 2 CHESTNUTXE and gerg reacted to this Share this post Link to post Share on other sites
Boingk 862 Posted January 3, 2020 As for firing order I believe there was a concern that the frontmost cam bearing was copping too much of a flogging, what with the chain and firing order and all. So they changed it to the 351 order with the next major redesign and that was that. 2 CHESTNUTXE and gerg reacted to this Share this post Link to post Share on other sites

Or it ain't gunna matter really Sent from my SM-G570Y using Tapatalk Share this post Link to post Share on other sites
Boingk 862 Posted January 3, 2020 I'd go the ones in the top picture, the ones that clear the ports a bit all around, looks like they fit better especially around the coolant passage. I haven't dealt with wet manifolds before but presume you want a pretty good seal there to save leaks and stuffing around later. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,311 Posted January 3, 2020 it is the same gasket top picture on old manifold,same gasket on efi heads bottom picture. Share this post Link to post Share on other sites
Boingk 862 Posted January 3, 2020 Ah, right you are. Probably won't matter to much in that case. If you're super anal about it you could trim them but if the main overlap is in the head to manifold water passage you should be fine from both a leak and performance point of view. Mind you if you've got the correct ones coming in I'd wait for them. Hell, you paid for them right? Unless you want to do an intake swap in the future, then use the current ones and stash the proper set. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,311 Posted January 3, 2020 thats how i ended up with the 289 ones ,in the complete felpro efi late gaskit kit they have 2 sets of intake gaskets fkd if i know why ?? oil seal too,and some other crap. Share this post Link to post Share on other sites
