Well just got back from Florida, dropped off my 68 455 to Mark Remmel/cutlassefi for the once over, engine is destin for my 65 Cutlass
Engine had 96000 miles on it from a 98
Goal is 450hp/500+ft/lbs
0.030 over pistons
H-beam rods
Original Nodular Crank (currently STDs mains 0.010 rods)
Iron "C"heads, ported polished, 2.125 intake/1.68 exhaust
Edelbrock O4B intake (hood clearance concerns and got a deal on it at the Olds Homecoming show)
W & Z Exhaust manifolds
Roller cam and rockers.
Got a few pictures of the tear down looking forward to see how everything progresses
That valve train looks about right for 100k. Similar to mine around the same mileage. Idk if most of those intakes didn't get a good seal at the exhaust crossover or it was so hot it cooked the oil splashed on it.

little crusty
Regards,
Is this Marks shop in Florida? Looks like a nice virgin core!
I dropped it off at Mark's rental house, think he's doing the tear down there.I felt bad as crusty it was even after it was pressure washed.
Yeah the core seems pretty untouched, though the crank had 0.010 under rods, but still had steel head gaskets. I got it from the second owner, first was a funeral home, and none of the paperwork mentioned any engine work. Car had been sitting since 1985ish from what I was told and based on plates on the car.
What's the big deal about the big car ex mani's Joe...do tell? Hard to find?
Well, the RH manifold is the same for single and dual exhaust, and it's unique to the 65-70 full size cars. The LH center dump manifold was only used on single exhaust cars, but a pair of them make it easy to put an Olds motor into a street rod or similar vehicle that needs center dump manifolds. I've got a 52 Chevy truck that needs a 455 (admittedly, that project is somewhat down the queue...) and these center dump manifolds are just the ticket.
I believe the crossover is going to be filled as running a electric choke, larger valves, ported polished.
Manifolds are down with Mark, I'm in MI so PM me a offer and tell me who is closer and I can see what shipping will be. I am supposed to pick up everything mid to late September if that timing and logistics works with your timing.
Been a while, things taking longer than the original plan, go figure, guess Mark is having a hard time getting a cam blank, supposed to be available in another week or so but will see.
Guess my heads are done so should be getting pictures and details next week.
I’m in west Michigan and have a 68 455 with c heads as well - just curious where you took it for work? Wouldn’t mind having a place to go to for the future if possible?

Hi,
Yeah having Mark/Cutlasfi doing the build, he's down in FL as hard to find many builders that don't have some scary stories on the internet, believe all builders have issues from time to time, but from my research and from this site and working with him on this build so far handles the issues in the matter one would expect.
Only major issue was getting a cam blank, which affected everyone as there are a few post regarding the shortage. Which held up this build by a few months.
Edited: our cam was actually a Lunati core that cutlassefi got for us and had Howard’s grind with one of their patterns, it wasn’t a Howard’s cam core, which may help explain things more...

If its not a “4/7 swap” don’t sweat it, there isn’t much, if any difference at this power level.
To be honest there isn’t any power to be had at ANY power level. The 4/7 swap was more of a marketing scheme by Comp cams early on than any real gain in power.
I’m assembling it so yes I’ve had cams be off 10+ degrees as well, but most times I’ve actually found that it was in the timing set, not the cam. Lots of crappy timing sets out there.
But I have a question for you if I may, how old was the Olds/Howard’s Roller cam you had? They’ve been using this same core for over 10 years with no changes. It’s also the same one Erson has been using for about the same amount of time and it’s the only configuration I've ever known this particular core to be available in. Just curious as I’ve never heard that before.

Nice looking build, you won't be disappointed. Sucks that Mark is even having trouble sourcing roller cam blanks, not good. I am sure Mark told you how much he loves the OB4 intake. I imagine the 455 in a 65 is similar to G body for room which means a tiny 2" tall drop base air cleaner is needed with any decent intake. Glad it is back on track.

You don't run a 4-7 swap with a dual plane intake. I've seen Isky's off 10 degrees in the past, it was always the cam not phased correctly in the grinder, also known as operator couldn't give a - - - - about their work. Finally the Iskenderians took charge of their operation and put a stop to this BS.

I've read that when I was researching the whole 4-7 swap, though the premise would have you swap the other 2 so it would be like a LS firing order, but that's a long debate from what I've read.
The intake was chosen for a few reasons, hood clearance and I only paid 60 bucks, the intake will be getting some work done on it to work, believe the plenum will be removed, Mark would be better able to elaborate.
My original plane was a performer and milling down the mounting pad 1/2 inch or so but by the time I bought a new one and all the mods I'd be in it over 600 bucks, and this whole build was over my original budget so as they say ever dime helps, also look wise the car will look more period correct or day two-ish as they say.
I corrected the post above: our cam was actually a Lunati core that cutlassefi got for us and had Howard’s grind with one of their patterns, it wasn’t a Howard’s cam core, which may help explain things more...

I've had great luck with that 04B intake before on one of my cars.
You don't run a 4-7 swap with a dual plane intake..
On a std firing order 5 and 7 are next to each other, fire in sequence but are on different “planes” of any dual plane intake.
On a 4-7 swap, 2 and 4 are next to each other, fire in sequence and are on different “planes” of a dual plane intake as well. Please explain the difference in intake timing/reversion between the two arrangements to all of us because I don’t see it.
According to my cam grinder, you want to pull from furthest runner away from the carb first on the dual plane.
It’s the same in both scenarios dude. So in other words you have no substantiated proof of any difference in the two configurations. Just what I thought, your opinion, not fact.

Whens the dyno test????

You don't have the brain power to get into tech discussion with me on engine design. But your a helluva port matcher, Ill give you that..........carry on.
