My Chevelle build and spot to Rant

Grumpy · Nov 2, 2016

those are much more closely matched in weight,
than most factory connecting rod sets I,ve seen
btw theres a difference between grams and grains,
the difference is that theres ROUGHLY 15.4 grains =a GRAM
so your rod sets almost perfectly matched in weight

look at the links

That is a good thing might try to build a stand and balance them myself cause I can and will go to tighter tolerances

Strictly Attitude · Nov 2, 2016

I tried a few different ways to try to get an accurate meadure of the hevy side but with out a stand the numbers are all over the place

Strictly Attitude · Nov 3, 2016

The libary is a great source of info took out one of my favorite books but an updated version from last time I read it. This book is a must read for efi information and general tuning info that translates to any gas build.

Here is just a nice little chart of AFRs

Within 2 grams is what most manufacturers shoot for. You are there now.
You can try to dial them in closer, but it's probably not necessary for your build.

Before you start grinding, remember that your pistons will also vary. So you can
mix and match the pistons and rods (without any grinding/machining) and end up
even closer to perfect.

Photobucket is down today so I can't grab a pic of a stand for balancing rods but there should be a pic or two in my Malibu build thread you can see when Pbucket is back up. Should be able to make something pretty easily that will work. http://garage.grumpysperformance.co...bu-uncaged-performance-therapy-project.10976/

Got some more toys

Ford 39lb injectors got 8 of these. Bosch makes them and ford rated them at 39psi so they flow closer to 42lbs all depending at what psi you set the regulator at.

These are the molex connectors for the EV6 injectors still need the rubber grommets I will be ordering more metri-pack connectors for my wiring. Buying in bulk is allot cheaper then ebay kits.

These are gen IV LS1 coils I got from Lance at pantera efi great price on every thing I have purchased from him. If you need any thing feel free to call them. The wiring harness is a builders harness but custom ones were available to be built per application.

These are the MAT (manifold air temperature) and CLT (coolant temperature). Lance also sold me these notice these came with the pins and metri-pack connectors for my wiring.

And my second wideband sensor these are nice cause they will convert to lamda for my ecu. They use the 4.9 Bosch O2 super accurate and fast.

Stay tuned for very soon I will have my intake manifold, crankshaft, rod bearings, and maincaps.

Grumpy · Nov 7, 2016

looks like a great project please post a good deal more details and pictures as you progress...

BTW how much do those sets of ford injectors go for $$
what does a set of the individual ignition coils and connector harness go for$$
and what ignition controller and magnetic pick-up will be used ETC.. LOTS OF DETAILS PLEASE

and

do they plug in with out any major mods required to the corvette style or TPI fuel rails/manifolds
(most do but there are exceptions)

I will grumpy really excited about having sequential efi with coil per cylinder ran at a high resolution

Strictly Attitude · Nov 25, 2016

Ok Grumpy I paid $296 for the injectors after hunting around the wiring harness was $125 I priced out what it would cost to build myself and not worth it those 25 pin connectors are expensive and then add getting the wire on top of it. Was worth it. The temp sensors were $20 for both. And $200 for the coils. Ignition is controlled by the pantera efi ecu with the 58x or 60-2 reluctor wheel. I will be using a vortec distributor capped off for a cam sensor to tell the ecu which cycle the engine is on for starting purposes and to drive the oil pump. I stole the ecu off ebay for $135 heck of a deal for an $1850 ecu. The fact it was lesser known helped hugely. But from what I gather through my own research is that the resolution as far as timing accuracy is amazing on this unit which really makes it shine.

I just finished my rods up getting them pretty closely matched I see why they are done to the half gram or gram cause even after buying the proper stand it was hard to get it down to .1+/- . I know it is as close as I can get it each right around 453.8 on the big end and each weighing 640.90 exactly to the hundredths.

The Crank is ordered costing me around $620 is ultra light forged crank internally balanced 3.750 stroke and Lance will be balancing it before shipping it to me. I will also be getting my pistons through him.

The machine shop finished up the installation of my splayed caps using arp stud kit and did the bore job so I knew exactly what size piston to go with. It is now .030 over. The cost of machine work came to $733.65. They recommended running thread sealant on the outer bolts cause of how close to the coolant jackets they run. I did the three center caps I put allot though into doing the caps and lucked out finding caps for real cheap through a friend. I was also concerned with cap walk being a stroker application. If it was gonna stay a 3.48 stroke I would have felt more comphortable with the 2 bolt mains.

The plan is the minimize quench running real cose to the head I will be spinning this no more 7000rpm.

these threads may be rather useful
BTW great deal on the ECU

More info on the injectors

39 lb/hr, 4-hole, high-impedance fuel injector with USCAR electrical connector

Original equipment on 2003-2004 SVT Mustang

INJECTOR NOTES:

Medium length injectors are for use in GT500 or Ford GT. We also use the MU32 in our 3v supercharger kits.
The long injectors are the more common length and are applicable to all non-GT500 Mustangs since multi-port injection was introduced

About electrical connectors:

The USCAR connector is sometimes referred to as EV6, which is a Bosch term for the generation of injector.
Jetronic is the older style connector, sometimes referred to by the Bosch generation EV1.
Neither EV1 or EV6 is technically correct because those generations of Bosch injectors could come with either connector. However most EV1's commonly seen use the Jetronic connector and most EV6's use the USCAR connector so it's easy to see the connection.

Ford injector flow rates are quoted at a delta pressure of 39.15 psi
so 41.1 lb/hr. at 43.5 psi

ideal for 525hp and using fuel pressure you can tune them to different hp levels

thanks for posting the related useful info

Strictly Attitude · Nov 28, 2016

I have also been doing some planning for other aspects

Loves302Chevy · Nov 28, 2016

Somebody knows how to draw. Unfortunately, the best I can do is a bad stick figure. Good for you.

Strictly Attitude · Nov 28, 2016

All back looking nice and pretty back to block prep still need to get it decked down to 9.000 deck height but wanna get all my grinding done on it first. I at least now know my specs to order my pistons. Soon I will be able to make this look like an engine again.

I really like that interior concept!

Those aftermarket 4 bolt main caps are sexy to me. Is that weird?
