Mild performance rebuild SD
I'm curious if anyone else has tried to run with any success speed density with a mild engine build. My truck is a 1992 5.0 e4od and I acquired a 1993 5.8 from a local gentleman for a good price with pretty much everything from the fan to the bell housing. Our local Napa automotive distributor is also an engine machine shop and they're rebuilding the motor. The lower is to remain stock less being bored and honed .01 over. The heads I ordered are Edelbrock 60379 with a Combustion chamber volume of 60cc. Estimated Compression to be low 9's and the cam is Edelbrock's performer plus 2182 (more or less an RV cam) also have MSD coil and distribute. I plan on retaining all of the emissions (for now)and will be purchasing a set of Gibson headers but. I'm going to purchase a 1992 ECC for 5.8/E4OD and attempt to run this set up, of course if it doesn't work then I'll have no choice than to convert to MAF. If anyone else has had any experiences trying this please chime in.

That cam is a bit much for Speed Density based on the LSA of 112 degrees. General rule of thumb is 114. But you have cubic inches and relatively mild duration @.050. Adding the heads and headers might be borderline for working with SD.
My 2 cents....it's a waste of money to keep the factory 5.8L EFI truck intake. Complete garbage.

My thoughts on keeping the factory efi intake was to keep emissions and I need the ecu to run the e4od and electric fuel pumps. there is always the aftermarket efi later if money is available. If SD doesn't work I'll spend the $700 and get fiveologyracing's MAF conversion. Right now I just want to get it in and functional.

A few recent builds have used a 5L upper intake and port matched the lower. Personally I think it's ugly, but the folks who have done it are happy with the results.

This build should make 350hp give or take and that isn't a mild upgrade from stock, it's beyond what 19lb injectors can supply actually. But the stock truck intake is gonna strangle the motor a fair bit so that will work in your favor for the time being, put a better intake on it and you will definitely need a computer and fuel system upgrade.

I've already started looking at using my 5 liter upper plenum and port matching the lower although the amount of grinding involved almost warrants spending the $700 for the Edelbrock performer intake. Yes I figured already I'm going to have to step up to a 24lb injector and after all the input I'm getting it seems like attempting to run on SD would be a futile attempt at best.
Toss on the Typhoon that Paul has, you will have a great combo.
