Aluminum 416 is about $500 more through Thompson motorsports. can you make a iron block into a 416? I'm not familiar with that. Complete shortblock from TMS 408 is around $4,000 and that's a new block. By the time I put rods and Pistons plus have the block checked out hell I might just as well do a stroker idk.

If I go stroker I just as well go big or go home

Do you have a LQ9 with flat tops with the 243 heads to get the 10.7:1 compression ?

Well I had a 347 with a D1, and now have a 416 with an F1A, and although I'm not pushing my current setup, I gained a solid 100ft/lb of torque throughout the entire rpm range.

With the 347, I had 3.73 gears at first, but went back down to 3.42s, and still felt like I had enough low end torque. Maybe it was my top end package, I don't know, but now it's even better. I rarely ever find myself 'needing' to downshift, even if I'm cruising in 4th at 2000rpm, it has plenty of torque, especially on the street.

Here's a comparison of the two setups:



The blue line is the 416/f1a, and yes, at 4000rpm, the torque goes flat because the tires actually spun on the dyno, then hooked back up by 5200.

My point is, the 6L is going to be plenty of fun, especially with the 3.73s.

HOLY SMOKES LOW END ! what do you have on top of that 416??? And why did you switch when you already had a forged ls1?

Well, my forged Scat rods I guess didn't like the 760rwhp, and they bent, and ended up snapping one cruising home from LS FEST 2 years ago.... it was 1:30 in the morning, 4 hours from home.

On top of the motor is a set of MAST heads, cleaned up and worked locally, as well as a MSD intake manifold.

How about a 370 and an F1D that comes on earlier for the torque?

High dollar setup you got there. Not sure how ported 243 would work on a 416

Probably better than you'd think. I know it's not 100% comparable to what you're trying to do, but Lil John did a test on a Procharged setup that had TFS LS7 style heads I believe and switched them out for TFS 245cc cathedral port heads, and the combination picked up something like 100rwhp.

Do you what your compression is with the new 416ci ?

It's 93 pump gas/methanol safe.

It's less than a stock ls3 motor.

How much power are you wanting to make? We did 800rwhp/700ft lbs in a cam only LS2 w/ a D1 on E85 in a 05 Vette M6. It was making 750 at 5800 rpm on pump gas but we dropped the boost some and tuned it on E85(flex fuel mod)

I'm not sure what the difference is in the Procharger but yeah I'd want whatever comes in faster.

I put a pencil to this and here is where I'm at with using a 416 from tms:

Procharger kit used: $4,000
TMS 416 LS3: $4,500
lonnies double pumper kit: $1625
FIC 80# injectors: $599
ls7 head gaskets: $60
ati balancer: $409
oil pump: $150
head studs: $300
Martin smallwood Cam from cam motion: $500
LS7 lifters $100
Boost gauge $200
A/F gauge $200
Kooks 1 7/8 headers $979
Kooks true duals $1765
meth kit: $800
Tune $500
TOTAL:::::::::::: $16,687 roughly. OUCH

The thing is by the time a guy figured up a good set of rods and pistons for the current 6.0 I'm not sure if a guy will save anymore than $1,000-$1,500, and give up at least 100hp.

The F1D is supposed to bring boost and power earlier in the rpm range VS the other F1 blowers.

We have 94 octane at Sunoco station's here in Indiana too, we're lucky to have it available to us. Bob

It does, but keep in mind it won't be able to make as much boost up top as an F-1A will. Bob

I know we have been emailing back and fourth, I have only quoted the short at this time. We can likely help you with lowering the overall cost here, Give me a shout and we can go over potential areas that we can save you some money.
Thank you,

On a F1a with say 12 lbs of boost, what is the approximate difference in boost in mid range between the F1d, as well as up top?

A few lbs?

Thanks
Troy
