What to do¿

[Thumprkils]

when you chage the tails shafts out the toqure bar will go on fine

[Thumprkils]

bracket n all

yep the only other concern is the lightweight fan and its height

this is all good to hear thumprkils.this may take a few months to complete but i plan on doing a basic play by play of the whole project complete with mispelled text,and poor quality photography via the internet to hopefully raise a few eyebrows.I know for a fact that the catalina motor has more than 400 foot pounds of torque at like 3200rpm(lol).The pontiacs lost a lot of balls after 73,but since its a 1970* i may luck out and have a halfway decent set of heads.This might be kinda neat by the time its all said and done.

what about the fan?can i run a high volume electric fan?i already know its going to take fire and a sledgehammer to fit the radiator in it but whatever ya know,all in the name of HP

Im not using a stock torque arm mount tho.I made mine i have a picture of it im my gallery.the four bolts that hold the tailshaft on,are same that bolt on the torque arm mount,instead of having two bolts holding the mount to the tailhousing,my torque arm mount bolts to the actual tranny case,using the four tail housing bolts..

hey i just noticed somthing.Both of my engines are from 1970.Could this catalina have the same engine casting codes as a 70 judge?

[Thumprkils]

well look on the side of the heads, there will be a # like 7j2, or 4x, or 6x, then go back to some of my old threads to find out a lil more, I have 4 full 400s
the first of which I owned I added and edlebrock preformer ,a quadra jet 700,it had 7j2s,and nothing((81 formula) on the road ever gave me any worries, my heartbreaker which i havent finished(heartvalve slow me down)(but tomorrows ram air will certianlly bring my passion back up)yet, has another edlebrock preformer, Qjet,292 lanati cam, 6x, along with the posi low ratio rear end, well you know,thats all you need, the stock intakes are very heavy, so go to the preformer n q jet, it should rock a buncha peoples egos

[Thumprkils]

everybody will keep talking bout flow, follow the reply above, put stock exhausts on and forget it
any more power than what itll put out is really
getting well beyond what needs to be runnig the streets anyway

[hotrod_chevyz]

oops its a 1972 model...

[hotrod_chevyz]

the heads on the catalina say 7j2 on them.It was rated at 200hp.Thats a lot weaker than i had in mind.i found that none of the v-8 pontiacs ever got past 400 hp,except

1962 389SD 385,405HP(62) 540306,544127 2.02/1.76 67

and the strongest they ever put in production it would seem is the

1963 421SD 390,405,410HP 544127,9771980 2.02/1.76 64

whats with that?not even the SD455 had 400hp?

1973 455 290HP(455SD) 16,X(rd port) 2.11/1.77 111cc

is this some sort of a joke?here is my catalina motor

1972 400 200HP 7j2 1.96/1.66 8.4cc 96cc

somthin aint right at all.That catalina will straight up smoke a stock 350 i dont care what the charts are saying.How can such fast cars be so underpowered?
