6.0" connecting rod so the dwell time at tdc is a little higher. Its definitely in cam timing events. The only solution may be a cam change.

Either a cam change or lower the static compression by 4/10ths. That drops me back to where I was with the original Vortecs and a XR276HR (10:1 rather than the 10.4:1 I have now). I drove that thing cross country more than once with no detonation trouble.
Thanks for the feedback. This latest build has been a pain in the ***. I hope to sort it out over the winter and be good to go next season.

Looking forward to your new engine build.

Started fixing up the set of Brodix heads going on this engine, one casting was good, the other one however... not so much. It became the victim of a dropped intake valve.



Seats cut out and major damage ground out. Ready for welding.

skinny z

Wow. Is it worth it? I suppose working in an engine shop has it's advantages though.

1986Z28OWNER

iTrader: (1)

Well a replacement casting from brodix is about 700$, all im going to have into this one is the cost of seats and guides.

skinny z

I was thinking more along the lines of what it would cost for a guy like me to have that head saved. There's a lot of time and skill that's going to go into that head with welding, milling and grinding.
Then again, like I said, working in an engine shop has it's advantages.

Wow amazing build. A lot of great work. I like to see fellow Canuck so well represented. I bought my Camaro this summer and it looks more like your first post! Seeing yours coming together makes want to get after mine!

The_Whipp

nice work dude and very nice car

skinny z

What's the plan from here? Go at it with a die grinder to get the chamber shape? I suppose you might have to mill it first?

1986Z28OWNER

iTrader: (1)

Surface it, rough it in with a die grinder, install seats and guides, cut valve job, finish chamber, match cc's, apply boost, run 8's.

Finished pulling out the engine and trans, sold lots of parts off the current combo. ordering lots of new parts for the new combo. Should have a nearly complete engine by christmas if all works out.

I also got some specs on the new cam, I had Lil Johns Motorsport Solutions spec the solid roller out for it, He does alot of turbo combo's and his camshafts seem to work quite well. It's a Bullet grind 0.683"/0.683", 261/265 @0.050", 115+4 LSA. Should be pretty nasty.

Well... Things took a turn for the awesome yesterday. picked up a set of CFE/BMF 18 degree heads. this thing should make some pretty killer power now...





Might need a lower profile elbow to clear the hood....






Xceldyne belt drive.



new camshaft from Lil John Motorsports Solutions


Should sound pretty badass through dual 4" downpipes dumped under the fenders


And some shiny bit's to match the new paint.

iTrader: (13)

that grind was spec'd with the other heads in mind, right? how much is going to be left on the table with it? you going to have another one ground?

1986Z28OWNER

iTrader: (1)

I may, Just for the sake of not blowing another 600$ I may run it this year. Even with the camshaft being a poor match It will be making more then enough power for the block to handle. Next winter I will likely upgrade to a Iron eagle or Little M with a 55MM cam tunnel and 0.937" keyway lifters.

More parts...

I still love what you're doing here, been a while since I checked this out, you've made alot of progress and it's coming along great! Awesome build!

1986Z28OWNER

iTrader: (1)

Small update... more parts arriving. I intend on stripping the panels back off the car to prep it for paint and take the plasma cutter to the front end to male some room the turbo kit and drysump setup.

Dual transmission coolers because I intend on street driving this thing a lot. And locking trans dipstick.


2.5gallon meth tank for street driving.


rebuilt the t&d rockers. Changing the exhaust rockers to match the intake rocker ratio, had to replace one shaft.





Got the correct brackets for my barnes pump and test fit everything with the k-member...

This build is going awesome, congrats! But how did you fab the radiator support so you can remove it for ease of engine access? did you just cut and make tabs? If you have covered this already i'm sorry but i read through it pretty quickly in between classes the other day and found myself reading it again today!

Sold the old engine and got some more parts in.




Billet 1x cam sync distributor.



holley 58x crank trigger. Has some slight clearance issues with the drysump scavenge fitting.



Logged the rod bolts on the rods and honed the small ends for proper pin bore clearance.



Got my 1.6 ratio exhaust rockers and got those installed.

I really liked that old engine. Any idea what it's going to be installed in? (I'll be cruising Edmonton in June. Might be a good race depending...).
You've got a lot of work in front of you. Any projected completion date?
It all looks like great stuff. Long live the Gen 1 SBC.

Last night I did some drysump pan surgery, the crank trigger bracket didnt clear one of my scavenge fittings on the pan, so some surgery was in order.

The clearance issue...


Took this trashed pan and stole some fittings from it.


My good pan, before cutting it up...






Big ole hole cut in the side, revealing the top scavenge line...


Fitting in place


Line re-routed, needs some minor fit and finish work and final welding and the pan will be ready for powdercoating.





All ready for welding.


This took about 4 hours in total, I was nervous about cutting the pan up, but it worked out quite well.
