Isky super 88 cam Hi Can I get peoples opinion on the Isky 88 cam, i really like the note and was after something that has a bit of note to it at idle. Im currently getting a new engine built. 59A Eddie Meyer heads and duel intake Scat 274 stroker kit. Duel 94 carbs Stromberg ignition Twin exhaust system The engine is to go into a 1935 3 window coupe running 39 gearbox and original rear end with 3.54 ratio. Is this cam streetable or is it going to be more of a pain and i should option for something like the isky max 1. Any opinions are really appreciated as i dont want to make the wrong decision . Thanks. Graeme
Do a search on current quality. There's been some comments in the last few years. Hopefully Isky has fixed what was wrong.
I have done a search but there isnt alot said about the 88 for streetable use, theres a lot of mention about the max 1. Hence why i was asking for peoples opinions who acually have that cam. Thanks
I did mention the 1007b but my engine builder said i wouldnt be happy with it,(sluggish under 2000rpm ) Hence he suggested the 88 instead
I am sorry to be the one to tell you but you need a new engine builder if he said that. That cam was designed for the exact engine you are building and for short track where you need all you can get from idle on up. It has a .007 max. lift velocity which no other cam in it's class has. It happens to be one of the most popular street cams in an under 300 ci flathead in the USA. You won't be able to get one from Isky though.
In the old "how to" hot rodding books of the fifties and sixties there were graphs showing the projected horsepower of various cams. The graphs usually started at 2500 rpm to show the gain over stock, and went up to around 5000. Below 2500 many of the cams available deliver less horsepower than stock. Finding real performance figures between 1500 and 2500 is difficult or near impossible. What I am trying to say is be honest about the way the car will be used, it's gear ratio. and take that into consideration when making your choice. All that said, a radicle cam can sound real nice with straight pipes.
I had Dennis Fring's built me a 276 inch motor and I decided on the 88 for the street motor I was shooting for.
I'd really listen to what those who know cams say. There is a reason why folks keep going back to them for cams. They know what they are talking about from real world experience.
Perhaps there is confusion about the multiple 1007 grinds. Of the three, there is a lot of variation. Remember, a "hotter" cam in a 274 will behave differently(milder) than in a 221 or 239. Maybe even more important is to consider your compression. Due to overlap, the bigger cams(duration-wise) will generally like higher dynamic compression. I have limited experience but some of the Max 1s and 88s I've heard purr like a pussy cat. Sound in a flathead is a major consideration to me. Regrinding is also an option as there are tons of choices. IMO, that would be considerably cheaper - less than half of what Isky is asking for a cam - QC issues aside! JMO, D
I've got a Max 1 cam in my '47, it's very mild. I've got the 88 in my roadster and the thing really rips. In fact, I grenaded the input shaft two weeks ago with it. I'm also running 4:30 gears, so I'm not sure how it would perform in a heavier car with a higher gear ratio.
I'm pretty sure he's asking @Automotive Stud what the engine specs of the engine in his roadster are, not the O/P's planned engine build.
My motor is stock stroke, bored .040, Isky 88 cam with adjustable lifters, Zephyr valve springs, Eddie Meyer heads and intake. It also has exhaust port dividers and an aluminum flywheel. It's got exhaust out the rear but no mufflers. Here's a video of it running. https://youtube.com/shorts/M_YVhF6VfWg?feature=share
Very nice car. Don't want to hijack the OP's thread but is there a story behind it? Lots of chrome and looks like an old magazine car. Sounds pretty good. I wouldn't call that a radical cam and in a stroker would likely be pretty mild. D
Can someone help me learn how to upload a video to Youtube? I'll gladly post a vid on my 292 running the Potvin 3/8ths. It sounds like a flat out race car. I started it up this weekend and an old timer in my neighbor ran over. Couldn't believe it was a flathead. It sounds downright angry and pulls like a freight train. I couldn't be happier with my cam choice. Mic on phone doesn't do it justice. When I started it up for my Pops, he jumped when I whapped the throttle. LOL! Exhaust is headers to halved '36 drive shafts. No baffles.
Anybody know the lift.......duration.........LSA of the Isky cam? They use to grind most all their cams using a 108LSA. (that's where the 'lick' comes from!) I'd research the specs and then call Delta Cams and price out a re-grind with those specs! Maybe bump up the duration or tighten the LSA to get the custom soud you want. Good people.......
Isky 88 Intake = .320" 264* (224* @ .050") .010" lash Exhaust = .320" 264* (224* @ .050") .012" lash 111 degree lobe separation.
Thank you, I built the car about five years ago. I was really going for the 1955 magazine cover look, and I guess it paid off, it made the cover of Hot Rod in March 2021. Thanks for the compliment!
Sounds pretty durn sweeet to me! I'm sure the Alum. flywheel affects the idle some. I'm not a flattie 'expert' by any stretch but....can you modify the ignition curve in those like an OHV /SBF engine? Lighter advance springs more initial advance without too much total advance? It made my SBF a totally different animal(or pony!?!) 6sally6
