seriously..... if you are considering building a motor similiar for your car- i suggest you START with a $10k budget

If you (anyone- not just you) think that $10k is outrageous....stay on the porch because you in all honesty aren't ready to play yet.

alot of people (mostly kids imho) look at the cost of a shortblock and think thats all they need to TRY and come close to these numbers they see on the internet...... They don't take into account heads,exhaust,fuel systems,induction,tuning,valvetrain,drivetrain ,etc etc etc.

is that $10k+ for a professional install or do it yourself?

when I built my LT1 (granted it was an LT1, not an LS1, but LS1 prices have come down since I did my LT1) I built a forged stroker, fully ported heads, intake, custom cam, full valvetrain, with full exhaust and a built transmission and I still didn't top $10k but I did the majority of the work myself.


getting back to topic, awesome numbers. cant wait to see what she does with a more revised cam!

you can factor in the price of install.. but with serious motors like the 408 with l92 heads (although those heads are CHEAP) with the l76 intake, headers, fuel system, ect ect ect you cant expect to be UNDER 10 grand.

A built stroked lt1 should be around 6-8 grand. But a 408.. ALOT more. but the horse will be better too.

You hit the nail on the head. If it is one thing I hate the most, it is the people that don't realize how much this **** costs. This is not a cheap hobby...if you like cars, and want to modify them, but don't have a lot of money, get an R/C car.

damn you guys made me recalculate roughly how much I put into my LT1 firebird. im glad I dont have a wife or she would kill me


but you're all right. I tell my friends all the time that it takes alot of cash and patience with this hobby. takes some good budgeting and sometimes periods of time living like a hermit lol.

the price to build an LT1 compared to an LS1 is not very different.
383/396 stroker LT1 shortblocks approach $4000, iron 408 short blocks cost about the same. GOOD ported LT1 heads with a custom cam will set you back $2000. the L92 heads and a cam will cost less than that. L76 intake will obviously cost more than a ported LT1 intake. everything else is similar in price. valvetrain/injectors/throttle body/headers/tranny/stall/fuel/rear. but in the end you're right one will make alot more power

gotta say... at first I wasn't impressed with the results... but looking a little more closely, this looks like a setup with a lot of potential!

almost 500 foot-pounds of torque to the rear wheels is quite impressive

kinda makes those thinking of a mild FI application think twice.. heh

yup, you gota sit back for a second and examine the graph at first. Then you see the power is only at 5800 and you smile.

I thought that you have to run the ls7 rockers due to one being offset? What are you running for rocker arms?
