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
