has anyone used one of their short blocks? seriously looking at their iron block 427 with upgraded pistons for nitrous use.

That long of a stroke probably wouldn't be good for nitrous use

ditto on that. It wouldn't leave alot of piston top/ringland room.

If you look at TSP's site they say the same and that's with a little bit shorter stroke.

I too have wondered about schwanke engines but haven't heard anything about them

I am too, looking at their iron 427 SB and trying to gather information https://ls1tech.com/forums/generatio...get-427-a.html


I would not spray the 427. I was wanting a nasty sounding NA motor than ran good for the 69 camaro. I would like to get more information on oil consumption issues and longevity of this long stroke combo AND hear more about the company. OP, I would stick with an iron 408 for spray....

Don't see whats wrong with spraying that 427ci. 4.125 strokes have been getting sprayed to death for years. As long as the piston is done right for it.

thats my thinking. I'll have them change the pistons to a piston designed for nitrous. I really would prefer a lsx454 but not in the budget. I haven't heard of anyone using theirs engines & am looking for someone that has to find out about their quality & customer service after the sale.

They've been in business for 23 years, i'd say they're doing something right. The price is right for sure.

They build a lot of engines for dirt track racing. Those engines take a ton of abuse...

the stroke/piston compression height has little to do with n2o use.
a correct tune and proper fuel enrichment for the n2o, with evrything in order. should have no problem hitting it with a strong dose of spray.

And design it for that short cylinder.

I have a couple buddies that have purchased engines through the years from this shop and let me tell ya it's not pretty...........................

I'd guess that depends on how much is sprayed. A piston designed for that stroke is less than optimal for a big hit of nitrous. The breakover point and ring package have to be moved up, putting the rings closer to the crown (ie more heat) and reducing the ringland thickness, and yeah, even the compression height is left at only ~1.00", which is more common for a naturally aspirated piston.

There's actually a good bit of info on here about that, mostly from Erik (Racer7088). He really seems to have what works and what doesn't work figured out.

I know some people have different opinions on this but ask some reputable shops why they wouldn't reccomend or warranty a engine with this much stroke on a big shot of nitrous. If your using a ERL block with extended sleeves than it may be a different story but people have been wary of going over a 4 inch stroke on stoke sleeve length for a long time.

Let's just say I can name 4 people off the top of my head that wouldn't buy a tricycle that was assembled by them and leave it at that. If you want to waste your money and have nothing but issues then don't say you haven't been warned...........................

Are these people on the board? Let's hear it directly from them and their experience, good or bad. These boards are suppossed to help each other out, and by saying "I got a friend" who had a bad experience, but no details is pretty weak. If you are going to make statements, then please provide details, names, photos, etc.

There is no one business who will ever make 100% of their customers happy, no matter what they do. And yes, sometimes shops screw up, it is how they handle their mistakes that "make or break" them in terms of a good shop. If they have been in business 20 something years, they must make MOST people happy, right?

Please note, that I am very interested to hear more, as I am a potential customer.

How much N20?

150 shot might be OK but 300+ wont last long.
