Scott: The power it makes is not the RPM type power we get out of a Honda
where you have to buzz the motor up to feel something. This is a torquey power
you feel in the seat of your pants. Although it consistently pulls in the 8.5
second 0-60 times the impressive part is that you can pull away from a light
in third without it shuddering (with a stock TR3 gearbox and rear end). When
driving, if you want to pass you simply push the go peddle, and you can feel
the grunt pull you around the other cars in a flash. It doesn't sound much
different than a stock 83, 86, or 87mm car, it just honking pulls you around
with authority. If building one for myself I wouldn't hesitate spending the
extra few bucks.

Hi Ed
You said << This engine pulls like a mule. >>
I'm just curious what that means in comparison to modern cars since I've
been thinking about a possible TR4 street car project.
What kind of acceleration (0-60) would this sort of set-up provide?
Scott B.

Tim: I built a TR3A for a customer using Ken's 89mm's and his Erson cam.
I
used Joe A's lightened flywheel and stock exhaust manifold with stock
1.75"
SU's on the short intake.I did nothing to the head.This engine pulls
like a
mule. I built it because the customer saw a TR4A I did with a Judson
supercharger and kept insisting he wanted the same for his "3". I kept
refusing to do it, and promised him more power and torque in a normally
aspirated engine for half the price or I'd build the replacement engine
for
free. I haven't had to do that. This engine easily out pulls the
supercharged
engine, without any of the probelms we've had with the supercharger and
it's
manifold. The 89's are well worth the extra $500 over a set of 87's.

I'm planning on rebuilding the engine in Ryan's street 1964 TR4. We're
thinking of putting a set of Ken Gilanders liners and forged pistons in.
Is
there any downside to using the 89 mm liners versus the 86 or 87 mm
liners?
If the 89 mm liners are used is there anything else that would have to
be
changed? The car has the Stromberg carbs and he has already put a 4
into 1
header on it some time ago. Had to, the cast iron exhaust manifold
cracked
in half. We've already gotten one of Larry Young's 270 cams for it and
plan
to mill the head slightly. The 89 mm liners would bump the CR up to 9.5
with the stock head and I was thinking of milling it to go to 10 to 1.
I'd
appreciate any thoughts/advice from the group on this.
Thanks,
Tim
