Project "Sleeper" - 69 Camaro updates

[BBC69Camaro]

Well I finally decided I needed my own project thread rather than keep posting updates to my welcome thread:
https://lateral-g.net/forums/showthread.php4?t=12701

For lack of a better project name, I chose "Sleeper" since I want to keep the stock look of my 69 Camaro but modernize it with more HP, better brakes, suspension etc. Obviously if you look closely you will notice it is not stock, but hopefully to the casual observer it will look like a stocker. I am still considering putting full Z/28 emblems on it and a 302 cowl decal just to throw one off further.

Some pictures of the car:




It is a 69 Camaro with the RS option with a cowl hood, automatic (700R4) and white interior. It has some z/28 Emblems that the previous owner had put on them. I was also told that it had a early 90s restoration done to it. I think the guy I bought the car from got it running again (bought it from a younger guy) and flipped it. I base this on the general state that the car was in (all the fluids hadn't been changed in a long time, radiator was just about rusted out etc). But that is okay, I was looking for something that had a really good body but needed an engine. I was still able to drive it home just fine, although it had some electrical and carb problems later and sat.

Overall the goal is to do as much work myself as I possibly can, both to learn how to do it and for the challenge.

I enrolled in a local JC and started taking automotive classes as I really hadn't done stuff like this before and really wanted to do it right. So it didn't take long for me to pull it apart anyways:

Old engine and trans, and old tired 307 passenger block from a late 70s early 80s car and a 700R4 trans:



Originally the plan was just to build an engine for the car, but that snowballed (more about that later). So I started building a big block to drop in the car. It is a 454 GenV block I found at a junkyard (took 4 tries to get one without cracks in it). It is bored 030 over with a stroker crank making it 489ci (8.0L).

So starting on the engine blue print, it is magna-fluxed, sonic tested. Mains, cylinder bores and deck are checked for straightness to get a baseline (pretty good but some machining is in order to make it perfect):



All the machining is done by me in my engine machining class (except boring and honing they didn't have that machine at the time).

Nice fresh block (with Por-15 engine paint on it; I just love this paint, you can hammer it and pour brake clean on it, doesn't phase it):


Custom grinding was done on the top of the block for increased oil return and a screen kit is installed (case I grenade a valve it will save my bottom end):

[BBC69Camaro]

Bottom end goes together:


All the main bearings are clearanced within .0001 of each other, for very even oil distribution. The goal is not so much max HP but a high HP build that will be very reliable.

Brodix RR-O heads are purchased. Out of the box they have a horrible run-out on the valve seats (max of .009; when we want to see under .002 at least; ideal is under .0005). The guides are honed, valves are checked (they are really good less than .0005 run out on the valve face). Machining the valve seats is done and a run-out of under .0005 is attained. The heads are surfaced (the surface wasn't perfectly flat, plus wanted to raise the compression just a tad).


The intake and exhaust ports are ported and polished.


The chambers are cleaned up and CC matched within 0.1 CC of each other. The heads are vacuum checked (20in of Vacuum they seal nice and tight). Should have a real nice and even compression ratio across all cylinders of 9.8:1:


Cam goes in:


It is a Comp Cams "Thumpr" roller cam 227/241 @.050 547/530 lift 107deg lobe separation. I went with the Thumpr as from my understanding a common weakness of a big block is it lack of exhaust breathing. My hope is that with the 107 deg lob separation and the increased exhaust duration that this will help correct some it.

Pistons, rods and pins are all weighed and measured. One Piston was a bit out of spec but JE in Huntington Beach swapped it right out for me with a smile, even giving me one that allowed me to get my piston to cylinder wall clearances all within .0001 of each other.

Pistons are SRP forged, crank is a Eagle cast crank good for 750hp (since I am not building a high RPM motor should be good), rings are Perfect Circle moly and rods are I-Beam Eagle.



Pins are installed, rings are gapped, rod bearings clearance like the mains to .0001 of each other.

Short block is together now:






Oil pump is a Moroso high volume with pickup and wind age tray.

[BBC69Camaro]

Heads go on, nice shot of the custom grinding both on the block and heads:


Verifying timing:


Intake is port matched to the heads and goes on. Full roller rockers (Comp Cams) with 1.7:1 ratio. Edelbrock RPM Air gap:


Valve and timing covers go on (Trans-dapt powder coated valve covers and GM stock timing cover for a GenV motor painted with left over Por-15):


Valve covers are crappy and leak and replaced later but the intake sure looks nice (durashine finish):

[BBC69Camaro]

Water pump (Stewart Components Stage 2 pump) and MSD Distributor go in:


March performance pulleys for v-belt systems and Holly Street avenger 770cfm with air cleaner go on:


Hooker ceramic coated headers with 2” primaries and 3.5” collectors:



Finished product ready to start up:

[BBC69Camaro]

After initialing firing up the motor on an engine stand, all the problems found were fixed (bad radiator cap, leaking valve covers, spark plug wire holders that let the wires hit the headers etc)





Fast Air/Fuel meter and dual wideband O2 sensors are installed, along with Pypes Race-Pro mufflers (went with their 3” stainless exhaust kit as well):

Should be about 600hp and 600ft-lbs of torque at peak at the flywheel and about 500ft-lbs off idle!

Special thanks to my school and instructor(s) for teaching me and letting me work on my car in the shop.

Ready to put in the car now. But wait all the brakes and suspension stuff will be easier to work on while the motor is out…

[BBC69Camaro]

I can’t put this nice new engine in an engine compartment like this:


So off the front clip it goes:


Needs paint badly:


[Bad pic] Once cleaned up and painted looks like new:

[BBC69Camaro]

Time to take a look at the front suspension and firewall, just about everything needed attention (new brakes, ball joints bushings etc)




Lets pull the front sub-frame. It needed some minor welding to get it back in shape:


And start cleaning up the firewall:


Front clip back from the powder coaters:

[BBC69Camaro]

Hmm, now I have to get new wheels and tires to fit the big brakes.

Since I am going to have to buy new wheels anyways might as well mini-tub the car so I only have to buy wheels/tires once.

That part of the project can be found here and was done up as a mini-tub guide:
