xagt's(351 4v manual) ate everything .
you cant compare a "restricted" 351 to an"unrestricted" 308.
unrestricted the 351 eats it as it should.the only car
I remember that used to beat 351's was a hatchback torana
"worked" off its face..with rego plates"EAT351"(S.A.)
Plenty of storys out there,but GT Manuals were hard to
beat,but they did have problems,I had an XAGT(RPO 83) and efn thing used
to break down regularlly.
.I now like Holdens,but I am a
realist.

I'm not talking about the strangled, gutless ADR27A examples with awful manifold. What i'm referring to is the 250hp, 9.7:1 1975-1976 pre ADR27A engines. These engines with twin exhaust were pretty good things and were only in 10/74 LH and HJ through to approx 6/76 HJ and LX. The improved power and torque of the HJ 308 was one of the 2 x reasons for the fitment of the TH400 box in Holden and Statesman.
RIGHT YOU ARE but with the TH400 box that was a power robing hopeless box compared to the good old trimatic high performing but weak box. why did they have that slow power robing slush box in the HX-Z,WB,VB. when holden got the friction plates sorted and you used a oil cooled the trimatic was a good box. Aussie road test were not very good in them days, how many times did they have a bad example, not running right but went ahead with the test. or just a gutless example. And we never tested the full potential like they did in Europe mags.

Just on about std cars hear now. The XB GT was not restricted it had good 2V heads but a std cam with lower compression just like a 308. Don't get me wrong i like the 351 even in the XB it's torque and the mechanical collopy & exhaust note make a 308 sound like rubbish and a ford C4 T bar auto makes a the holden auto's just a poor joke.

Falcon GT of the show room floor are standard. but 4speed all have the 4v heads and some of the first autos did to, but around mid 1972 the auto went to 2V heads but had 4BBL.

The HJ 308 with the 9.7:1 comp got a bigger cam than the HT-Q 308 it has one cast ring on it, but holdens spec on the grind is a joke as it's point of reference. it would be good to see it measured at 0.002 or 0.006 at least to get a better idea of what it really is.
My 308 was a std Gem reco 0.030 over and the cam grind was what ever they spec they grind up ? back in 1983.
Interesting that the HT-Q std cam is the same as the 308 HT-Q but only the timing is advanced and the HJ on 253 gets a smaller cam.
