Jeep Strokers

Hi guys thanks in advance for your help.
I have a dead stock 1997 tj. I'm looking to bolt on a later model intake and new headers. I'm also planning on bolting on an elderbrock head.
My question is. Has anyone done a bolt on elder Brock head and dynoed the results ?
I can't find them any where if they have.
Was it worth it. How was the mpg afterwards

Thanks

I don't think anybody in here has. They bill it as a stock bolt on replacement so it should work just fine, but I don't think even Edelbrock had posted any claimed dyno gains and I'm sure they would if their were. I wouldn't expect much unported on a stock 4.0 other than the weight savings. Just 2¢ from somebody who has never even seen one in person.

I'd expect the gain from an Edelbrock head alone to be about 10-15rwhp. The gain will be greater if you've already added upgrades to the intake and exhaust systems, and adding a performance cam will further increase the hp gain from the head.

Wax,

In my opinion dropping a Edelbrock head on a stock 4.0 short block for performance advantages isn't cost-effective.

I'd choose lower-cost external bolt on upgrades such as your header that would crossover to a potential stroker build in the future.

Lots of information on Dino's site with budget friendly recipes

Thanks guts for the heads up " scuterneeing the intentional pun "

I will check out that site. I thought the better shaped combustion chamber may help the economy as well as the power. It's very hard to get a stroker crank down to Aussie due to their weight. And I had been considering turbo with an aw4 upgrade on the gearbox.

Ignore some of the misinformation like how no 4.0L had dowels and their choice in a stock timing chain. It's a 4.0L build with a stock eddy head.

They do reach their 242 HP goal (1hp per CI)

Nice find. Interesting video. I wish Russ would start a YouTube show for our strokers lol.

Nice skyline by the way, I have an r32 myself, I was wondering why you had a screen name like that

Thanks! Took me a second to figure out how you knew that. I guess those pics don't work anymore thanks to Photobucket trying to put themselves or of business. What kind do you have and where did you get it?

Im in australia so not so as hard to get over here as in the usa

I have a r32 gtst with an rb30 bottom end with a rb26 head
Ported head by myself
750 cc injectors

n1 r33 turbos

r34 gtr rims on a back skyline
r33 gear box

Its a great drive i love it

It isn't difficult to get 242hp from a 242ci engine. You can reach 220hp with just simple external bolt ons, while adding a ported head and performance cam should yield another ~25hp.
With modern medium performance N/A engines making 1.2hp/ci or better these days, 1.0hp/ci is nothing to write home about but it's still a big improvement over the 0.8hp/ci that the 4.0 came with from the factory.

Your Skyline sounds a lot like what I had built. I like it

Is the only thing keeping you from doing the stroker the additional cost of shipping a stroker crank out there, or just finding somebody to go through the hassle of actually getting one to you? I know it would be more expensive but I'm pretty sure it could still get to you via USPS Priority packaged up and under the 70lb limit. How much do they weigh? If the package is less than 70lb, I would guess it wouldn't be more than a couple hundred bucks tops. Not THAT much in the grand scheme of things, especially considering you are willing to drop the coin on an Edelbrock head.

A 4cwt 258 crank would weigh about 50lb with packaging, but a 12cwt version would be at about 70lb.

Both of which are hard to find not I think too. How about the Scat crank?

I shipped a Edelbrock head last week to Australia.
Just over $400.00 utilizing my FedEx commercial account.

Because DHL specializes in international shipments, might be a tad cheaper.
I'm currently looking into the most cost efficient shipping rates.
