I decided to sell my previous motor & start with a seasoned "010"
4-bolt main block out of a 75 pickup truck. I decided to order up a 383
stroker kit. the kit is externally balanced & features a forged
steel crank, 5.7" forged steel rods & Keith Black (kb111) .100"
dome pistons. Minor grinding of the oil pan rails was required
for the crank counterweights to clear. A Melling M55HV high volume
pump keeps it oiled feeding from a stock sump pan. A Comp 284XE Extreme
Energy camshaft(240/246 @ .050", .507"/.510" w 1.5RR) was chosen
to pop the valves open in the World Products Sportsman II cylinder heads.
I decided to use ARP hardware to keep things tight featuring a main &
head stud kit. A Streetdampner keeps things balanced & looks sharp
in the polished finish with a few coats of clear to keep it from rusting.
On top, was an Edelbrock RPM intake topped with a 770cfm Street
Avenger Holley carb. The plugs are lit up by a Holley Strip Annihilator
ignition system. I chose this ignition box because it had many features
which could come in useful in the future. Features include up to
20deg of timing retard on startup making it easier for higher compression
engines to turn over and allowing you to run as much initial as your engine
can take without having it lock when trying to start on those hot days.
It also features 3 rev limiters including a main-overrev, a line
lock limiter & a transbrake limiter as well as 2 separate RPM activated
switches which can turn a component on or off at any desired RPM.
The Strip Annihilator is used in conjunction with a Holley Laser shot 500
coil which feeds an MSD Pro Billet Distributor firing through Accel Spiral
Wound wires. The system is nice although i have sent the box back
twice to Holley for repair. Apparently there is a recall on some
components they used. All this would come to breath through 1 5/8" headers
and into 2 1/2" pipes leading into Flowmaster 2 chamber mufflers.
It was an interesting season to say the least. When I put in
the new motor, I had replaced the motor mounts with some Energy Suspension
inserts. The motor mount pads although would not sit into the inserts
properly so they had to be trimmed. Well I am assuming I trimmed
them too much because this motor ended up breaking 3 different transmission
bellhousings. With that & other problems, I could only
muster a measly 13.4 @ 101.3 mph with the setup.
The converter was way too small for the cam . My season ended short
on October 18th 2001 with yet another broken bellhousing. I had decided
to call it quits for the year & possibly sell the car in the spring.
Well what can I say, I didn't end up selling! I sold the
Crager chrome rims in the winter & bought a set of Aluminum Z-28 rims
which needed to be painted. In the spring, I decided to pull
the motor & swap out the Energy Suspension inserts for some new GM
Heavy Duty rubber mounts and found some used motor mount pads since I had
to cut the others. I then invested $2200 CAN into a 700R4 fitted
with a Vette 2200 stall converter (still too small). Well that turned
out to be a nightmare again! I went through four 700R4's in the matter
of a month. Although the shop held up their word & warrantied
every one of them, it was still very frustrating. After the
fourth one broke, I decided that I wanted them to build me a th-350
instead. The th-350 was fitted with a manual valvebody & another
2200 stall converter(I am hard headed!). Well guess what, two
turbo-350's & two Intermediate sprags broken. This was all with
street tires, as I hadn't even put the slicks on it yet. They
built me yet a 3rd th-350, but before they installed it, I supplied
them with a brand new 10" 3500 stall converter I had purchased.
Finally I had the whole combo & knew it was good for a decent slip
if these transmissions would hold up! In the meantime, I bought a
set of M/T Et Streets(28x12.5x15). I had decided to take the
car up to the track that upcoming weekend and mounted the new slicks on
the car. Well it was a Saturday & also track time! I arrived
home from work at 1pm & immediately started preparing the car by dropping
in fresh oil (as I do every time before the track), checked all the
plugs and everything I could think of at the time. Before heading
up, I decided to take the car for a test drive and make sure everything
was normal. One launch with ET Streets was all it would take to break
yet another bellhousing. At this point, I just laughed to myself
and said "As If!" There was no warranty on broken bellhousings
as the internals were still good.
Well I pulled the motor again! This time I yanked the motor mounts
& pads from both the frame & the block. I ordered up some
Moroso steel motor mounts & pads. Dropped these new mounts in
along with the motor & a used transmission I bought from my friend.
This transmission was rebuilt a year before he took it out of his pickup
truck. It sat in his shed for almost 5 years before I bought it.
Cost me $100 for the th-350 & $52 for the Hurst shift kit I put in
it. The power train went in on a Friday night, the following
day i checked for leaks & took her for a test drive. Worked excellent,
shifted excellent. Incredibly, I went to the track at about
1pm that Saturday & came home with a best slip of 12.8
@ 103.9 mph!!!!! Finally, after almost 2 seasons
of bad luck, I finally hit my goals of breaking into the 12's.
That was a very exciting day, I felt an awesome 1.74 60-ft
time which was accomplished on a bone stock 81 Z-28 suspension
including rear factory air-shocks. Being used to my previous
2.0 60 ft's, it was quite the shock when I launched!. On a side note,
I think it would be a good time to put subframe connectors on the car soon
since its launching that hard out of the hole! That converter was
an excellent purchase, it was worth every dollar.
Being very excited about the new times, and surpassing my goal
of 12.99 I decided to borrow my friends Victor Jr. intake manifold.
That week, I swapped out the RPM intake & bolted up the Victor
Jr. I arrived at the track the following weekend & took my 1st
run, 12.9 @ 104.1mph. It was a tad disappointing but i had
not touched the carburetor jets or timing yet so I knew things should improve.
A few jet changes & timing changes netted my my fastest pass of the
day, 12.62 @ 107.1 mph and a 1.7360
ft!!! Now i was really excited! After so much work
things are starting to pay off. My goal was only wanting a measly
12.99 out of the car even though i knew it should have been better than
that. I'm sure with a few more hours of jetting & figuring what
kind of total timing the motor like with get me into some 12.50 or maybe
even 12.40 passes. All that's left is time, and there isn't
much of it. In another week I'll be heading up to the track
again to try & better the time.
