Guys,

I'm looking to buy an AC Cobra replica with a Ford 351w. The engine spec includes Edelbrock Performer RPM intake and GT40 iron heads. Originally, the engine was supplied with a 600cfm vac secondary carb, but the current owner changed it for a 650cfm double pumper and this has me worried. Some guys on a Cobra replica forum have scared me with stories of premature bore wear with double pumper carbs due to overfuelling and bore wash. I must admit, when I went out in the car, the fumes from the sidepipes were quite heady and the car banged and popped on the overrun. The engine has covered a total of 11k miles, but I'm not sure how many of those were on the DP set-up (guesstimate around 7k-9k miles). There was no blue smoke from the exhaust and the owner claims it doesnt use a drop of oil. Also, the engine did feel very strong when he gunned it.

What do you think?

Cheers,
Ian.
