Well it's almost test and tune time here and I haven't done any work to my set up. Plan to pull eng today and at least change my converter. I have some other ?? I need help with before I put the eng back in.
1. If you use solid mt mounts should you also have a solid mount for the trans? Where can I order them? Have seen the front plate but was not sure how hard it would be to install.
2. For my combo is the 850 too much?
3. Have looked at a 174 Blower but was told I may have to much compression + the cost for the set up is high?
4. I shift at 6000 w a 6400 rev limiter but the eng feels like I could push it more--whats safe?
This is what I now have. I only run 1/8 mile.
351 W--30 over
SRP Flat top pistons
Victor Jr. Heads-60 CC
Super Victor Intake
Holley 850 DP-Mech. Sec.
MSD Distributor and ignition
CSI Elect. Water Pump
Crites Headers
Isky solid cam
254/259 @ .050
584/584 Lift
C-4 Trans
3000 stall--only can do 2000
462 Gears--8"
MT Drag Slicks--14" 26" X 8.5
3000 lbs
My best 1/8 is a 7.5
Thanks for any help.

No aftermarket solid mounts for early FoMoCo.
Left side brace easy to make.
Must use flexible trans mount with solid motor mounts and auto trans.
Prothane makes the right trans mount.
850 carb is too big in my oppinion.
6500 RPM should be fine.------------------

Carb is too big, convertor too tight, and it needs shifted higher.  For example, KK has run 7.55 with my '70 that weighs around 3200-3300 lbs, using a .030 over 351W with ported factory heads, a Victor Jrintake, a smaller solid cam than yours, flat tops, a 750 DP, and a 4.11 gear with 28x10 slicks in back. But, it has a convertor that will stall around 4600-4800 rpm. She is currently shifting it at 6000 with a 6600 hi-side chip in it. Ifit had more gear, we could shift it around 6400-6500 and I wouldn't worry about it.

yeah, forget the solid mounts, especially the trans. put a turnbuckle on the left side and roll with it. ------------------

Thanks for reply.
I put a chain on the left side but still can see some engine torque --will try a turn buckel. Will try a 4500 stall. Was told they could loosen it up. I'll also try a 750DP.

Nice thing about a turnbuckle is if they loosen up, you just turn them tighter.  SteveW

I like a solid strap (1-2 inches wide) or a nice aluminum "A" shapped plate.
Easy to fabricate and can all be bolted in.
From left head to frame rail. Piece of angle iron or steel bolted to frame rail to attach the plate. Slick and nice and neat.
Won't loosen up. ------------------

Wasent trying to be sarcastic . Do you think if I put a turnbuckle mounted off the side of the tranny,and tightened up the drive train, would it make D/T too stiff or could it help the car react?? I already have turnbuckles on motor.

I thought you were busting my balls Mike.
I think your car is leaving pretty decent.
I can't think of a better combo, other than I am not a fan of mid plates.
I recomended the strap/plate style brace for Jim as it is neater and more efficiant than a chain or turn buckle. They never get loose.I have motor plates and a stiff polyurathane trans mount on MM.
You have close to 400 HP on me, and I am about 150 lbs lighter than you Mike.
MM sixty foots 1.37-1.38 on nine inch radials. That is leaving about 6k on a good track.
52-5600 on average tracks with a 1.39 sixties.
Have you considered lowering your engine and trans? This of course gets the crank centerline more in line with the differential.
I found that to be a very effective means towards improving launch consistancy. We'll see how all of my chassis science gets applied late this summer when I try my hand at Hot Street.  We think we can go some low nine-teens with MM and 740-750 HP @ 2900 lbs or so.

We have already lowered motor. You know that doing so also affects transfer.Im Thinking we will need to see 1.25 .27 this year in H/S you got to make the car hook at 1500-1000 under flash good or bad track Im not unhappy with my 60's but you know racing.Looking forward to meeting you at the track this year ------------------

Just another FYI as long as you asked Mike.We tried several methods of trans stiffening.
From braces to solid mounts. None showed any gain. All caused case cracking issues, regardless of trans type used. 
Best we have found so far is pretty much what you and I have. Semi stiff trans mount and motor plate(s). Lowering our stuff helped our sixty foots. ------------------

I've been kicking around lowering my motor for a little while now. Would it be worthwhile at this stage for me to lower it?

That would be nice. That coupled with some chassis stiffening in front of the firewall should do wonders for how the car leaves, and how consistant it is, especailly if I build a bigger motor.

Mike D what type cage do you have in the car?
A full cage front to rear is the ultimate with motor plates tied into cage & frame. Stop all flexing. I run a solid trans. mount with no problem but I don't have a mid plate.You have to do what works best for you. No to car's are a like.Do you run removable weight in the car? When running in SS/M 3125 lbs my car likes the weight in front of the rear tires.In SS/L 2900lbs it like's it behind the rear tires. In SS/K 2850 lbs it does not like anything!!! Point being ,try moving weight around .

I used a solid mount when I ran my 408 before I put in mid plate. Then we went up in HP with the 400inch motor and had to go mid plate with flexable trans mount.Can't go any lower with motor.The oil pan is about 1 inch off the ground now. The 60ft numbers I gave earler were with a glide, 1.89 1st gear, and a 4.86 rear. Now that I have the turbo 400 things are going to pick up in the 60. Can't go into gear #'s on turbo. Someone might be lookin.  We have a cross bar under the dash along with shock tower bars.
I am in the process of putting in diagonals now. Mr Fomo,
I agree. Plan on doing a lot of weight shifting. We have about 250lbs to play with. Thanks, to everyone All suggestions welcome ------------------

Nah, those aren't a priority. The majority of flex I am getting is from the firewall forward.
