HEI on '74 SBC

Will this fit? My friend is looking to upgrade his distributor and it looks REALLY tight for an HEI but I thought I'd ask the experts :)

Thanks!

The HEI I bought off of Ebay from White Performance fit in my '73 blazer but it is right up against the air cleaner so you might want to go with a smaller aftermarket one. I can send you a pic tomorrow.

Watch the interference between the firewall and the disto and you can get air cleaners spacers or offset spaces to allow for the new HEI. Check Summit or Jegs.
