2004 wj stroker

Post by HCE » August 27th, 2018, 11:47 am

I have a 4.7 stroker with 9.5 compression with a delta cam 202/209 at .050 with .412 lift, heads have 2.0/1.62 valves mild porting to blend the larger valves. Only other item is a header that should bolt up to the cats. Injectors will be stock. The target vehicle is a 2004 jeep Grand Cherokee. Will the computer handle this engine with out needing to be reprogrammed?

I'd recommend camshaft upgrade for your 4.7 and something closer to a 27 pound injector.

With the correct recipe of parts you shouldn't need a tune

Camshaft upgrade a little vague. What your recommendation?

HCE,
Would be happy to make a camshaft recommendation.
In order to make a specific recommendation I would need to have more information than what you've provided.

You're welcome to send me an email or give me a call.

Thanks,

Took the dive. 4.0 came out 4.6 went in. Drives great computer handles it just fine. No pinging on 87 octane with 9.5 compression. If I get bored may try larger injectors in the future.

Stock injectors untuned? Have you done much WOT yet?

Stock injectors, no tuning and have not noticed any noticeable fuel starvation or other issues. Runs nicely to 5000 rpm, acts like a stock 4.0 with just more power everywhere. I was a little worried of the computer handling it as there is very little information out there with stokers and obd II. Not saying there might be a little more to extract with tuning, but this combo works nicely.

I cannot recommend strongly enough that you buy a wideband O2 sensor and at least look to see what AFR you have at WOT.
