I'm in the market to buy another fbody and found a seller claiming his has 400rwhp I was wondering if someone with more experience with built engines can give me an estimate based on the work done if his statement is true.thank you!


355 LT1
400 crank
forged rods
forged keith black double dished pistons
pacesetter long tube headers
218\224 comp cam (low policy?)
ported heads with ls6 valves
moroso cold air intake

Its hard to say , what the heads flow the actual cam specs,how hi its reved. Auto or stick, how good the tune is and what the entire exhuast is. Could be 300-365ish those headers are holding it back some, does it have EWP?

Either one or both of you are clueless and I would stay the hell away from the car unless it is cheaper than a stock one would be for the condition. It sounds like an under performing nightmare waiting to happen.

How is it a 355 with a 400 crank? If it is an actual 400 crank then anyone who had anything to do with the engine build is an idiot. If it is a 3.75" stroke with the .030" overbore used for a typical 355 then it would be a 383.

I hope the "double dished" cheap pistons are actual two valve relief.

Sounds like it would be missing a lot of critical drivetrain mods gears for an M6 stall and gears for an A4.

OP

seller needs to provide a "dyno" sheet that shows wtf power he claims it makes. Also a "build" sheet showing head/cam specs in detail, rod length, etc.

as caprice notes...some of the claimed specs don't add up

lmao when I saw 355 and then 400 crank I was done..Stay away from this thing..and double dish pistons lol,this is hilarious

Yea I did ask for a dyno sheet or proof of work done but he said he had everything done about a year ago.I just wanted to confirm with you guys cuz it all sounded fishy when he started going into detail.here's the original posting in case you guys wanted to see.

I'm just posting what he listed by text but yea he told me exactly that,he said when you have a 350 block and replace the crank with a 400 crank,and you bore it 30 over as well thats a 383,bigger crank gives it bigger stroke.

An actual 400 crank would be 2 piece rms, the whole thing screams "run".
