installing big block in my nova

[slimsls6]

Hello everyone. its been along time since i've been here, with family, ill parents and work. well finally getting back into the swing of things and got my new 557 built. i'm getting parts together so i can put this in my 72 nova. now my car is originally a small block car. my question is, can i still use small block core support with the big block and use stock fan shroud? i know big blocks are offset a little in the cradle, will this interfere with fan blade hitting the shroud? I really don't want to use electric fans, worse case, do i need to change to a big block core support and shroud? thanx in advance, Jim

You can have your small block core support made into a big block core support by NNN they do Novas only.

I used the SB core support when I did my BB conversion. All I did was make a pattern from cardboard of a real BB one, transfered the lines to the SB one and cut the opening bigger. I bought a repro BB shroud and hardware. Works fine. Also bought a BB radiator from NNN, which I still have,as I decided to run an aluminum one.

I would just cut the opening bigger to match the BB version, then pick up the BB shroud and the top mounting kit and be done with it.

Looks like Gobi Beige - very cool! [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

On my Nova, which was a conversion from a 6 cylinder to a big block, I didn't do anything and it worked fine? [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

You are just lucky Bruce! I've seen guys fight and fight overheating problems.

what was the purpose to offset engine anyways? was it for the valve covers to clear brake booster, do i have to offset engine or can i put it where the small block is?. thanx for the responses. also the car is in primer, house of kolor actually, epoxy. Jim

I think it is more to clear the steering box, it will be a problem using the small block mounts if you want to use big tube headers and power steering it will be a problem

Let's see an engine shot, then Benjamin can see how his dual quad setup will look on his '69 - someday!
