hold on here no stock block hmmm i have a factory passenger block no r3 now u know u got to spot me out

if my car was 2800 race ready with me in it oh boy people would hang them selves lol

Haven't weighed mine, I hope it's not 3300 with me in it. I bent the crap out of my 8 3/4 housing, twisted axles, and cracked pinion gear

wow really

I have done that too, now it's braced every way I could and tied pumpkin to spring perch with tubes

put a pic would like to see if u dont mind

Think I still have your number. I'LL text you a pic when I'm in the shop next

kool thanks

I've run my 340s very hard (past ~40 years) during Autocross and hi-speed road course lapping events... 4000-6000-6500-occasional 7000 rpms... for common 30-60-120 seconds of AX/HSAX lap times... road course lapping sessions for ~15-20-30 minutes... engine survives with modified baffles oil pan, diferent past cams from stock hyd to ~484 hyd ..... runs great! Planning a new SB possibly with Eddy alumin heads, maybe a stroker.

Hey all, FWIW I decided not to go with the half fill as per my machinist's (and most of every here) recommendation. I called up the fine gentlemen at Hughes who I take it have come across many big power LA builds. Their tech told me he didn't think the half fill would be necessary if I were shooting for around 700fwhp with boost. He told me, as I already knew, that the biggest killer of these engines with high hp/relatively low rpm boosted motors is detonation. I am hoping that with the combination of a front mounted intercooler, E85 and wideband tuned fuel injection that I should have an easier time tuning to keep out of detonation than some other setups.


I should be getting the motor back in the next few days. Still have a lot of work to do but hopefully I'll have this thing running before winter.

Seem to be holding up? I have another housing to use, but mine smashed both axle tubes about flat and started ripping the perches off. I was considering getting a housing jig and doing some serious bracing.

[s][/s] u on a trans brake

How fast are these cars or is that top secrete. Lol

foot brake, I leave on the kit when I spray it tho

top secret lmao

oh ok me to foot brake

Yeah, it's been like this for a couple years, has never shown any signs of damage since. I use a trans brake and an okay nitrous shot. 60fts good

I will not share that. My car runs okay and surprises most

I fix that statement for you

Update. Got my new housing, went with a moser 8.75. Scored a 35 spline setup at a swap meet. Got a set of billet caps/adjusters for the stock center from mark Williams also. They are back ordered so it's gonna be a month or so before I see them
