ok so im finally building my motor in time for spring/summer to get to my 750+ rwhp goal with my d1-sc at 15# i was hoping to get input and opinions on this build and if you guys would change or add anything to improve it without adding too much cost to it. thanks. the build sheets are attached.

*fixed the links, sorry about that. LINK- http://smg.photobucket.com/albums/v3...motor%20build/

I don't know if it's just me, but your pictures don't display so I can't see the build details.

I'm planning the same build, so I'm interested to see.

ill be doing the same build with the same goals in mind next year. 750rwhp. will need a double pumper and 90-110 lb injectors im guessing. a new set of fuel rails and fuel lines as the stockers are only good to 700ish per Lonnie. A 9:5 compression ratio will allow for more reliability at that level of power without having to rely on pure race gas. Ill be mixing my 111 in with the 93 ethanol free fuel I buy, and spraying methanol. Then its all up to the tune. I am still and will continue running a Mass Air system too!

I am going with a 3/4 decked head such as TF or AFR 225's
Diamond Pistons Dished
Callies Rods instead of Eagles
Katech Rod Bolts
Good Head Bolts
GM MLS Gasket
Cleavite Bearings and Mains
stock Crank machined and balanced.
Dual Valve Springs
LS7 lifters
Rockers.

Then there is the machine shop and labor provided you have someone do it for you. I will be dropping it, and tearing it down. I am not sure if i will buy a new cam yet as my cam is almost ideal anyways.

yeah im thinking i may need more injector, i have the 60# on there now but i think theyre only good till about 600rwhp so im thinking 90# should do the trick. your car right now is almost identical to mine lol i fixed the links guys and i put the link in there too just incase...

sorry about the pictures being blurry i couldnt figure out how to make them clearer.

i am looking for the same HP level. i also will be using the same D1 blower that u used to blow up my LS1...lol. i will be going with a 370 fully forged at 10:1 (due to high elevation), Patrick G custon cam, 317 ported heads. ported stock TBody, and LS6 manifold. i am unsure what boost i will see at 5400ft elevation...hopefully 12 to 14...?

i want to run no more than like 15-16 #'s i want to try and not work the blower too hard for reliability and longevity which is my main focus on this build. i would like to be able to go on a 800 mile drive with some highway pulls on the way if i really wanted too lol but also without going over the already high cost of this build.

As for the fuel system, 60Lb/hr injectors will get you into the 700's depending on your base pressure and fuel. I still run the stock fuel feed line and use the EVAP line as my return...its not right but it worked for the time being. I've made right around 830ish rwhp with the stock fuel lines. I would also recommend looking at using ARP Head studs vs using bolts, the clamping force is better with the studs. I can't see the build sheet lol

underpressureWs6

iTrader: (17)

yeah i was definitly going to add in the head studs instead of bolts for sure, the injectors i hope i can get by with if i can, yeah sorry the pictures of the build sheets are blurry i cant get it to be clear....

to me that is a lil much on the dyno tune. 800 for a tune is about double what I would expect it to be. And yes I prob will be using head studs too, and really that is what this post is all about, is learning what we all wanna do for this build. Reliability at 750rwhp plus is a feat, and if it can be obtained this is the place to talk about it at. as far as the 370, if i were to do a build like that, then I would go ahead and upgrade to f1, and push towards 900+ easily, but im not after max power with this car. just super fast and as much of a sleeper as it can be. im sticking with the stock cubes....because I like the idea of keeping the car the way it came as much as possible for selling purposes 20 years from now or more. id also advise a badass oil pump and a bigger drain pan if possible to compensate for the extra pumping capability. also, i run royal purple every 3000 miles. it is indeed the best oil currently on earth, due to its additive package. protects your investment for sure. and yeah i too was going to mention that 60lb injectors have a ways to go past 600. im going to drop mine myself and see how much that will save me. find a good machine shop, and see how low i can haggle that price. the 317 prc's are what i think BLUE was running, and they are great, but I have been advised by someone to go with a afr ot tf 225 series due to the thick decklid which will allow for the best seal and provide just a tad more reliability and peace of mind. and of course the most badass head gaskets you can get. mls and ls9 apparently idk.

well the blocks only gonna be punched out to a 352ci which works fine with me cause i also like keeping the car as close to stock size stuff as possible, the d1 can definitly make 9xxHP if i work it hard enough but i dont want to for reliability reasons. the build includes a melling oil pump so i think im good on oiling issues hopefully. the heads are going to be the PRC 2.5 ls6 heads which i think should suffice lol i would ideally like an AFR or ETP but definitly cant shell out anymore money lol

cars going under the knife in 2 weeks so if anyone can chime in to either modify or add anything i would gretly appreciate it. thanks.

Looks good.....I'm not sure on the 352ci though

underpressureWs6

iTrader: (17)

whats the opinions on the 352ci??

TermnEatr

iTrader: (24)

What cr are u looking for? With the -4cc pistons and 64cc head...

If I was u I would run diamond pistons or wieseco and ls9 gaskets

underpressureWs6

iTrader: (17)

im hoping to stay inbetween 9.7 - 10.0 on the Compression, are the ls9 head gaskets THAT much better and more reliable than the GM MLS gaskets??

TermnEatr

iTrader: (24)

Couldn't answer that cause I've pushed neither one to failure but its good insurance as is anything else. If you decide u wanna save some money u can ditch the lonnies kit and piece together Ur own dbl pumper alot cheaper.

I'm curious about the 352ci displacement. With the stock crank, are they really boring the LS1 block out ~0.030"??
