big block pros and cons ?

[Qdub24]

I think you will find that one part # fits full size BelAir type Chevys,F Body Camaro's and A Body Chevelles.at least the Hooker # 2455's do;

Those headers fit a wide range of cars. I'm using the ceramic coated version of 'em on the BBC in my '90 Caprice Classic (B-body). I got 'em from a guy that had 'em on his BBC in a '81 Z/28 Camaro (F-body).

By the way, a stocker 305 V8 radiator will keep a big ol' big block plenty cool.
Long water pump will clear/fit by the way. with a clutch fan even.

Well, I guess that depends on how big your big block is and to what extent your modifications are.
I personally wouldn't waste time running an original 305 radiator and if you are going to replace it anyways why not get a larger more efficient aluminum radiator instead.
And you are correct the long pump fits fine though mine is a little tight with my dual fan set up.

305 replacement radiators are of the aluminum tube fin design and wider than the V6 radiators. Mine may not be as radical as yours, but, it is 13-1 477 with a with .750/.738 roller....it gets street and cruise time, along with regular roller lifter changes. Rolling around with a loose converter and 4.10's will build some heat, but, no hassles, plus, here its gets hot in the summer(100-110 F). We'll see how the e85 affects the engine temp this summer...


**** NOT ALL A/F Body BBC headers will work in a G-body!!!!

Its the Hooker '70-81 BBC Camaro 2455 headers that most have the best luck with. On Chevelle specific headers, the front down tube is too far forward in the several sets I tried to fit onto my Malibu with the engine in the stock location, they may work if you are moving the motor back, but, the stock firewall does not offer much room for that. The '67-69 Camaro/Nova headers would not fit my car either...already went down that road. I did not try the new Summit or Heddman headers, just about 10 sets of used BBC headers I gathered up.
