355 stroker kit

[mr j-man]

just spotted this kit im not up to scratch with strokers at the moment so id like to know a little more! any thoughts an opinions would be great

Holden 304-308 5L Scat 355 V8 Forged stroker engine kit | eBay

If ya look around ya can get Scat kits the same as that for around $1400 but with hypereutectic pistons instead of forged pistons. If it's just for a tuff streeter ya prolly don't really need to go forgies.

yeah have seen a few cheaper kits around, forgies are only if you intent to run FI arent they?? might just sus out the hyp flat tops i think.

[mr j-man]

i seen multiple procomp kits gettin around very cheap to a point where its unbelieveable, and the amount of peeps buying them is quite large..... are they really that crap in comparrison to other kits??

[DANNY8]

Procomp kits are like $1000, Scat/Eagle $1400....I know which I'd go for. I'd stick with a stock 308 bottom end over a Procomp stroker anyday.

another question...whats the difference between H beam rods and I beam rods? also what would be the best type of piston?? im definately going with flat tops but ive seen - cast, hypertectic and 1 or 2 more other types?....never built or bought parts for a motor build from start to finish so im just tryin to find out what works best in a stroker combo before i speak to any builders and having them baffel me with info. cheers danny

Google "I beams" and "H beams" to visually see the difference. I'd assume H beams would be stronger, but again not really a necessity unless ur goin all out and spendin a shit load on ya motor and it's gonna make serious power.

The different pistons are mainly the alloy they're made from and the way they are made. Plain old cast pistons are just an alloy, hypereutectic pistons are also cast but have silicone in the alloy as well which I think changes the expansion rate of the alloy (ya can get a few sorts of these I think which vary how much silicone and other additives go into the alloy). The next step is normally forged, which is alloy, but instead of cast, it's stamped which compresses the alloy and makes it alot stronger, then I guess after forgies ya'd get billet pistons, which are a tad extreme.

If it's for a tough streeter, I'd just get a scat/eagle kit with hypereutectic flat tops. The reason there's a few different sorts which expand/contract differently is coz if u use normal pistons with forced induction, ya get a shitload of heat and if it expands to much it's gonna try and sieze up with it expanding into the bore and you'll end up breaking sumfin. Not just forced induction, but alot of revs will do it too. So I guess u either give the pistons more bore clearance so they have plently of room to expand (which will result in less compression), or u choose different pistons with a different alloy which doesn't expand as much.

All the technical shit is new to me, I ain't no mechanic and I haven't really played with that stuff too much, so not 100% sure. I only know a bit about it from an engine building DVD I bought only a week ago haha! If ya don't mind playing with motors ya should look into getting it too.

i just got a scat kit with "I" beam rods and haypatec pistons i think it was about $1300 for the kit + a couple of hundred for balancing... there is a few pics of it in the block on my profile... havent got it in the car yet but im happy at how the kit looks ... dont go anywhere near procomp ive heard nothing but horror stories.

where didya pick ya kit up from?? ebay supplier??

[juiceie vh sle]

i got it through a place here in S.A call chris milton engine development

[DANNY8]

My cousin is also gettin a kit from Miltons. Apparently they haven't got any at the moment but I rekon February is when they get more in.

I've got a brand new SCAT crank on its own for sale if you're interested? Mine is Chev rod journals, so all you have to do is buy a set of 5.7" Chev rods and a set of 383 Chev pistons. Steer clear of going Holden rods, you'll only regret it.

I'm only selling it because i'm going Chev.

hmmmm, if I were in aussie I'd grab that (assuming 3.48" stroke)

seems to be a lack of supply here in NZ

whats the go with 5.7chev rods and 383 pistons?? noones ever mentioned to me about chev parts used for the stroker...not even the machinist i was talkin to. Any chance u could give me more of a run down of the finer details and so forth?? thanks
....how much u chasing for the crank? how much runtime has it had?

When using standard Holden length rods (5.65") with a 3.48" stroke crank you end up needing a piston with a odd ball compression height. If you use a 3.48" stroker crank that is cast/ground to suit chev rods then you can use standard length Chev rods (either 5.7" or 6") and pistons (holden and chev use the same 9" deck height) which are a LOT cheaper and easier to get (including a much greater range cast, hypatec, forged in various Cr's )

Yeh, probably a bit much for shipping hey. Yes, it's 3.48" stroke (355).

I thought i'd been through this many, many times on here, but i'll go again.

If you buy a Holden 355 stroker crank with Chev rod journals, you can use off the shelf 350 Chev 5.7" rods which are obviously cheaper and you can buy any rod you want for a Chev. Then you can just run an off the shelf 383 Chev stroker piston (1.425" pin/compression height) which again, are cheap and easy to get.

That's the reason i'm only selling the Holden 355 crank, i have rods and pistons for a 355 Holden, but considering the rods and pistons are the same as a 383 Chev, i'm hanging on to them to build my Chev.

If you get a crank that has Holden rod journals, you are pretty much limited to the factory Holden rods and ACL or custom made pistons. Obviously it's a hell of a lot cheaper to run Chev rods and pistons.

As for my crank, it's brand new, still in the box. I'm chasing $450 for it.

That's a good price. damn shame.

I'm still undecided as i'm rather attached to my B cast heads so a stroker is a probably a bit much for em

[Blown V6 Hatch]

Early heads will flow enough for a moderate stroker, it'd probably be better with VN heads, but it'd work fine with B casties.

Edit: Not trying to make a sale, just saying that's all.

When I finally get around to rebuilding it, I want it to rev but it would require some real good heads to support a 355 @ 6500rpm+

I feel ya pain mate. It was only till a few years ago that we started to really get some good racing products and industries here in Oz... before that then you'd have to give your right arm for a 383cube V8. There should be some awesome engineering serviced in NZ as power boating is getting HUGE over there...!! I bet it wouldnt be hard to find someone to build you a ripper..!!

Fixed your post for you.

[Aussiepride5L]

LOL.... true that....!!! 100%.

[Aussiepride5L]

Anyone know of a good VT 5L engine/block for sale...?
