Nova going in under the knife Since no one has ever done an LS/Nova build, thought I would, lol
OK, its 2017, back to reality.
I have a 74 big bumper nova, 6 banger with turbo 350, orig 38K car, never touched (a shame, isn't it)
I have been collecting stuff, plus have left overs from other builds.
Orig I was doing a gen 3 5.3, gen 4 rods and flat tops, 241 heads, somebody's stage 2 cam, LS 6 intake, log manifold, VS 83/75 billet.
Narrowed 9" rear for better wheel selection, Moser axles, using the 9"
11" x 2 1/4" rear brakes, drums redrilled. Procharger 850 HP intercooler, Ebay score. Trans is 4L80E, Holley pan, mount kit, and Holley HP.
Prob do a bumper tuck, but part of me wants to leave it, lol
I have all the parts, was going to take the engine to the mach. shop, get it rebalanced for the gen 4 rods/pistons, new cam bearings, etc.
While the 5.3 would have plenty of go, I was just offered the top end off an LS 3-I had used LS 3 heads, intake on a 6.0 past build, now I am thinking I should hunt down a 6.0, lol-before this even really gets started I am changing direction, so i'll see where that goes-anyway, i'll try and post up as it evolves-money wise says stay 5.3, but who doesn't like a 6.0 with big port heads, lol

Thought I would lay out the mounts for the engine and 80E trans, was kind of confusing at first until I realized I had the X mem. upside down, lol-the bottom of the X mem. sits aprx 3" from the lower bolts on the trans rear housing, part of the mounting system bolts there. 74 is a little diff than 68-72, so the engine mounts will prob need diff holes, but the trans mount should help locate them-I was going to make my own mounts, but there was $$ in the budget for these.
Also found the truck acces. dr. wont work with an LS 6 intake, should have remembered that from other peoples projects-couple options, but I may just go to a vette access. dr-that wasn't in the budget, lol

Not sure on the paint yet, would need to be taken down to bare metal since small sections of surface rust-will see how bad the winter is, temp wise where I am at-need to replace my fuel oil tank, but it is half full, afraid to move it yet until its empty.
Decided to label the engine mount parts so I would know how they go when I drop the motor in. I bought all the parts listed for them, including the poly
inserts-not sure when they designed these if they tried the poly inserts, but they are not close to matching the holes in the engine side mounts. Only one way they can go, close to 3/16+ off-the logical part of my brain said get a stock clamshell mount and test the fit, the hot rod side said clearance them to fit since you have them, so I did. So now I have to wonder, did I maintain the same angle bet the engine and cross member, lol-these clamshell type mounts have to have the correct angle because they have tabs that rest on the engine bracket, prob not a good swap mount. I'll work that out.

Getting back on the nova, pulled the six banger, installed the 5.3 for a trial fit. I used the Holley mounting system, to lazy to fab up a set, lol
Anyway, they fit good, plenty of room for the 80E. I mounted up the turbo on the log manifold, it close to the control arm, might have to trim the arm or cut and tweak the manifold. The truck manifold hits the steering box, so i'll cut a window in my spare manifold, see how it fits-shouldn't be a big deal to make room. Looks like plenty of room for a 4" down pipe. Got a good surprise my sub frame had the extra holes that were used on 68-72 Novas, so my frame adapters fit w/o having to drill all new holes. The trans mount was a little confusing until I figured out how they went. Some of the bolts that came with it were to short, but hardware stuff. Next i'll install the new rear, set the drive line angle, and side to side meas, weld up the perches.

Spent some time setting up the 9" rear, installed the OTR multi leaf springs, adjusting the rear so it centers the wheels/tires in the wheel wells, also setting up the pinion angle. Takes some time, have to lower the car, install the tires, get the weight on the susp., look everything over, then do it all again until I am happy with it. Then weld the perches. Ordered the Jegs sub frame conns., not happy with them, prob. make my own or buy the Global West weld/bolt ones. Thought about diff traction bars, since it wont see much track time.
Might just build my own slappers. Couple of the pics show the Holley engine mounts, the two bolts are threaded thru the adapters and supposed to hang over, but it was noted that on 73-74's you have to cut off the bracket where one of the clamshell went-my 74 did have the 68-72 frame holes needed for the mounts. Also pictured was a truck manifold I cut up to see how much clearance to clear steering box-may make my own manifold.
