summit 8802 or LT1 hot cam
 

Any you guys have any experience with a Summit 8802 cam in a marine application? The 8802 is pretty close to LT1 factory hot cam....It's about the same numbers as a Comp 270 marine cam, but 200 bucks cheaper...A little more lift than the Comp cam 270, but still a 112 LCA.....Thank you..

Obviosly the cams are very similar in the specs. The differences will be in the lobe design amd quality of the cam core.

What cam core is a billet style vs cast? What spring rates are you running?

Lobe design is a big deal, but the real question, will the Summit cam last in a marine application?

Can you locate a used LT1 hot cam? Even find photos of used hot cams to see how they wear?

For $550 is the price for a quality custom cam from many of the good sources. Bullit, Jones Cams etc. Then you get the benfit of tailored lobe designs.

The cam core is billet..They have excellent reviews ..My springs can handle the cam no problem...I don't see why a Summit cam wouldn't last in a marine application? You just need to worry about reversion, but these cams are very similar in specs...You have to admit these marine camshafts are overpriced...500 bucks for a roller camshaft

The Summit cam quality has zero factor with the specs on your reversion. Neither does the 112° LSA. It's all about the total overlap for the application and heads used etc., that applies to your exhaust setup.

Haven't seen anything about your build or setup.

Your query was essentially about if you should go with a far cheaper Summit cam. Not sure what you expect for $500 ish dollars these days with a quality roller cam.

That's something you'll have to decide. Reviews are likely meaningless for your marine application, unless they're running circle track continuous high rpm racing.

Sir, you haven't been helpful in the least...It looks like you want to debate everything here...You asked about cam quality and I gave you an answer..You can figure the overlap based on the LCA and the duration..They are very similar...For the record it's a 383 with aluminum heads 2.02/1.6 valves and a stock Mercruiser exhaust...You apparently don't know the camshaft so quit trying to break my balls please..

Mariah,

Oh, my sweet summer child... :rolleyes:

With 15 posts (at the time of this post), your unawares is excusable, but you'd do well to stroll around the room and take account as to who commands respect and whose opinions add up. There are a handful of members here who actually do know what they're talking about, and you've just stepped on the toes of one of them that was actually trying to help you with your question. You're gonna find it hard to get much help if all you do is rudely dismiss it when it's offered.

Carry on....

Thanks. Brad.

I have not used Summit’s Pro camshafts. Therefore, no experience with’m. Just a statement to answer op’s question.

For anyone interested, here's an article on them:

Lift seems closer to the Comp extreme efi cams. I have experience with the extreme 268efi. Lots of boating hrs in fact. 268xfi hydroller 218/224 at .050 113lsa .570/.565 lift with 1.6 ratio rockers

But….it’s not the same cam is the summit one in question, so….i have nothing , really, for you.

Also, with stock exhaust ? Nope.
Not many (i really don’t remember any) have run any performance cam (218 at .050” or higher) , so you’ll have to do a real search to find some. I do remember a few using 212 at .050” comp cam marine extreme cams.

If one vs. the other is better suited, I wouldn’t let $200 stop me from buying such an important part.

Sydways,

Yup. This.

Consider what happens if this one little part breaks.... :popcorn:

Thanks. Brad.

I run a Crower hyd roller 221/230 @.050" and 525/545 lift on a 1.5 rocker, 377 stroker with stock (GLM) exhuast and 4" thru hull. Over 300 hours on the motor to date. No reversion issues. Just a data point

Well, I apologize if I was being off....I'm new on here obviously and don't know who the senior people are....My bad..

What heads ?
reason for asking is the better exhaust port flows out, usually the better in also. :yack

Don’t worry about that crap. You’re fine. :thumbs

dont know any thing about that cam but I have run 3 or 4 Summit flat tappet cams in the last few years. I used delphi hardened lifters and have never had failure on any of them. two were in different 454's in my jet boat and they both spent all their time at either idle or 5500 and they were not treated well but they held up fine. obviously they do not make them themselves and I dont know who grinds them for Summit but I have no complaints about them.

Skip White NKB heads with a 68cc chamber...About 9.7 to 1 compression....I having them build the bottom end 383 CI since their crew has like 200 years experience..Performer intake with a QJ....I think I'm just gonna get the comp 270 Marine cam..In for a nickel, in for a dime....Thx.

I don’t like skip white. He sucks and is a sell out.
That’s my opinion. We all have’m.

I hear ya..He actually has a good deal on a 383 short block..2900.00 not assembled....4 bolt main block, cast Scat crank and their 4130 rods and Wiseco forged pistons...He seems like he actually knows marine stuff...I didn't have much luck with Smelding....They don't like marine stuff and they weren't very open to the idea...As far as why I don't build it...Cost...I'm gonna have 2k in machine work on 2 bolt main block...thx.

I’d suggest an Performer Rpm over the standard Performer.

I don't mean to derail this thread, but to answer your question SB I have run two different sets of heads. First set were a pair of Dart Iron Eagle 165cc runner with 1.92/1.60 valves. No issues. Currently running some aluminum CNC AFR 195s with 2.05/1.60 valves.

Question...My old engine has a good set of knock off vortec heads... 1.94/1.5 that I mildly ported...Can't decide if want to sell that as a good running engine, rob the heads, or just pony up for some NKB aluminum heads...Not sure if I can get away with 9:7 CR on a cast iron head on 93 octane...They are obviously wuhan heads of somekind...They ran fine all of last season....Thoughts? appreciate it...
