can it be done and how easy is it? the engine bay is massive would be a cool car to throw a th400 in with a 454 and a 12 bolt and spray it till it pops or fly through the lights in 9 seconds with 5 people in the car lol

 

Oh im sure it def. can be done.

Look on summit or google motor mounts/trans mounts....headers are going to be kinda pricey though,just to warn ya.

 

yea i figured the headers were gonna be pricey im in the process of doing a 383 lt1 but i totally want to do a big block caprice drag/cruising deathmobile lol i heard you could use small block mounts and i could make a trans cross member

 

I'm sure you could just find a crappy set of headers that would fit ($ cheap). It would be cool, but such a ghetto ride...

 

i know i had an 86 camaro with a 350 with afrs and a huge cam and the car was 3 different colors also had a built 700r4 with a b&m megashifter in it was pretty bad ***, looking to do the same but with 4 doors lol

 

hilarious I found you in here, asking this question. I actually just got the opportunity today to buy a 454 from someone at my work for $100. and Im thinking of either putting this in my 96 9C1 caprice car, or maybe my truck (work truck). also I got an old 402 that I have tons of aftermarket parts on that would swap right onto this one. just not sure if my heads (that are ported and have SS valves) would be a good match. figured Id poke around this forum and see what I find.

 

there is enough room to fit a tall deck BBC in an F-body, so there is definitely more than enough room to do it in a B-body.

The BBC uses the same engine mounts as a Gen1 SBC, but the LT1 is different.

I have seen a few big block conversions to 80s and 90s B-bodies.

 

The lt1 has the holes drilled and tapped for the gen1 sbc clam shell engine mounts.

ask me how i know

 

What kind of heads are they? If their factory,whats the casting #?

 

yay GM heads, off a 402 from a 71 chevelle. casting #3993820. I believe these are small valve heads. oval port with the open chambers.

the 454 has oval port heads already on it. the ports do look the same. but the heads on the 454 have nasty ports (due to poor casting) that may be what mine looked like before the porting. I dont have any port flow #s yet, but the job looks really good. I had a guy in my class do them way back when I was goin to comm. college.

just saw your sig, awesome. so since you got the exact setup Im wanting to do, can you break down your combo for me? is that a retrokit roller cam? or a factory roller block? what headers? itll be a strip car. no heat or windshield washers and gutted.
