I'm about to start looking into a lq4/9 stroked to 427 for boost. I'm looking at a f1a or 88mm turbo at about 14-20lbs whichever can get me to 850whp easiest. I want to be able to do this on pump gas so i know i need the lower CR. Help me make the right choices here. Opinions welcomed!

Texas speed 427 rotating assembly:
Eagle 4" crank
Eagle H beam 6.125 rods with ARP 2000 rod bolts (are 8740's better?)
Wiseco 4.125" -23cc dish pistons
Wiseco steel top 2nd ring
Clevite H chamfered main and rod bearings

Parts needed:
317's unported. (i know people make good power with these but do i need a 70+cc head?)
(need help with valvetrain!!)
SLP double roller timing chain & oil pump
"9" rear
walbro twins
fast fuel rails/ 60 lb inj.
6L block

Parts on car:
tsp 1 7/8 LT's w/ true duals
fast 92/92 unported
built t-56
Moster stage 4 clutch
many suspension mods

well i kinda don't want to lose all of these parts which is whats swaying me more towards the procharger vs turbo. If i'm forgetting anything let me know.
Thanks!

60# wont do it, I would contact a sponser that does sleeved blocks. is the crank a 4.125 ? if so look for a sleeved block. Turbo vs supercharger is a old debate either would get you want ya want. The supercharger is easy to package, a turbo would require a kit that is well built contact kypt ,or modular turbo.

You would be better off just getting a 427 lsx stroker. Dont waste money getting an lq block sleeved when the lsx is already ready to rock.

I don't think you need 427 inches to get 850 hp. A 370 or AES 390 can get this done for a lot less money. You might need a bigger blower than an F1A to get this high in rwhp.

Definetely go with 80 lbs injectors and I would strongly suggest methanol injection. A 408ci at 9.5:1 compression with an F1A and meth will hit your goal no problem.

only do a 427 if its sleeved otherwise your going to crack the block most likely. but thats going to cost tons of money. the beautiful thing about boost, you dont need big cubes like n/a guys do. you could get it done with a 370 or 390 as others have said. the aes 390 is a VERY nice shortblock.....
