F.A.Q.
Q: I was wondering how you made your corvette come out the way it did in certain aspects, mostly height and appearance. Did you lower the car with a specific spring or other? Carlos
A: No magic was needed to nail the right stance. I simply went with Vette Brakes & Product's Performance + suspension kit. The kit comes with adjustable composite leaf springs in both ends. I set my front end to almost the lowest setting by adjusting the spring end bolts. I also went wit 11" rear spring bolts at the back to get the rear end low too.
Q: I have a 79 vette and would love to purchase aluminum bumper as seen in the forum. Did you make these? How can I get something like this? Tony
A:Hi there Tony. I did indeed fabricate the front and rear bumpers out of aluminum. I used the stock units as templates and worked on from there. By doing it this way you will still be able to use all stock mounting points and if wanted you could still you the front bumper as a vacuum reservoir just like stock. I'm not planning or making more of these or selling them, it was very time consuming. Jay
Q:
I am giving serious
thought to getting a roller cam to replace the factory
L88 cam I have now. Which roller are you using? Is Crane's
roller setup capable of living in a street application?
I have heard that they have no oiling problems at idle
speeds, unlike other roller lifters. Did you use their
lighter pro lifters? I heard that they are less than
100 grams in weight each which would make them about
the same weight as a normal solid lifter .Chuck
A:
I'm using Hydraulic Roller Tappet Camshaft from Crane
Cams (#CRN-139741).
Basic

3,000-6,500 RPM. Intake Duration 050 inch Lift: 234
Exhaust Duration 050 inch Lift: 242
Duration at 050 inch Lift: 234 int./242 exh.
Intake Duration: 296
Exhaust Duration: 304
Duration: 296 int./304 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.610
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.632
Valve Lift with Factory Rocker Arm Ratio: 0.610 int./0.632
exh. lift
Lobe Separation (degrees): 112
This
cam is very much streetable as you can see from my dyno
charts the engine made tons of torque on very low
RPMs and kept doing so till very high. I have driven
the car in stop and go traffic, no worries I have raced
it hard, no worries. The cam works great on all kinds
of driving and I'm very pleased with it. Lifters I'm
using are Crane Cams Hydraulic rollers (#CRN-13532-16).
They are designed to work well with my cam and the rest
of the engine. I also added set of Crane Cams Chromemoly
pushrods (#CRN-13628-16 ). Jay
Q:
Any thoughts on how the Stahl headers are going to fit
with the Steeroid's rack & pinion? My
Stahl headers should be delivered some time in the next
week or so and then I will be converting to the R&P.
The kit has been sitting in my garage since Feb. 02,
waiting for an excuse to be installed. While I wait
my thoughts vacillate between there will be absolutely
no interference between the two to the opposite extreme
that headers and the R&P will occupy the same space.
I did talk to Eric @ Steeroids last week and he thought
that there would be no problem. I will believe it when
I see it. Ken
A:
When I did my Steeroids Rack and Pinion conversion awhile
back I had to massage one of Stahl headers(#215)
primary tube on driver side so it wouldn't touch the
steeringrod/joint coming from the R&P. Other than
that they were a nice match. Jay
Q:
I
noticed these two pictures in your recent post on the
corvette forum. I am wondering what backspacing you
are running on the rear wheels? I would like to go to
5 inch backspace but am wondering about the clearance
to the frame.
Also, in case you are wondering, Quickor Suspensions
can make you a custom sway bar so that you can run even
more backspace. It looks like you have room for at least
an inch more backspace if the sway bar wasn't in the
way. Chris
A:
I'm
using 5.5" backspace with my 10x20 rear wheels.
Notice that I'm also running HD offset trailing arms
from Van Steel. I have had several discussions about
this and few people have told me that it can't work
and I just keep saying it works fine. I'm not using
any wheel spacers or adaptors, so my true backspacing
is the advertized 5.5". It is a tight fit that
is for sure. The tightest spot is the spot just above
the trailing arm pocket I only get about 1/4" clearance
on that particular spot but that is fine. I'm using
a 3/4" Rear Sway Bar from Van Steel and it clears
the wheel and tire by 1/2", 5.5" is the maximum
backspace I would ever use with stock from and offset
trailing arms. Jay
Q:
I am interested in the firewall cover plate. I will
soon be installing a Vintage Air unit in a 76 and would
like to know more about your unit. Have you posted pics
on this topic on an archived thread? I wanted a flat
firewall as I'm installing an LT1 and 4L60E. Steeroids
is installed also. Any info you could share would be
of interest. Coolant and refrigerant hose routeing looks
to have been a concern for you also. Thanks in advance!
Terry
A:
I
have made a topic about the cover plate, but I'm not
sure if it is in the archieves. Making of one of those
covers is relatively easy. I just took piece of card
board box and draw and template on that, cut it and
then used the template to get the final piece out of
sheet aluminum. Jay
Q:
I
noticed on the CorvetteForum that you have information
on an electric headlight conversion for C3 Corvettes.
I would be interested in this info if you could pass
it along to me. Thanks, John
A:
The
electric headlight conversion was just what I was looking
for in my search how to get rid of all the junky vacuum
operated stuff on my car. I got the whole system from
a good friend Chris McDonald at McSpeed. Chris is the
geniuos behind this system and you might want to take
a look at McSpeed website for more information! McSpeed.com |
